If the perimeter of the
rectangle is 36 inches,
what is the value of x?
X-3
7x+5
Answer:
x = 2
Step-by-step explanation:
To find the value of x, we simply need to use the know values for the lengths, widths, and perimeter of the rectangle.
The formula for the perimeter of a rectangle is as follows:
P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
Let L = 7x + 5 and W = x - 3
Now, we will simply plug our values into the formula and solve for x.
P = 2L + 2W
36 = 2 ( 7x + 5 ) + 2 ( x - 3 )
36 = 14x + 10 + 2x + -6
36 = 16x + 4
32 = 16x
2 = x
Thus, we have found the value of x to be 2.

solve for x if 10/4x-3 = 2
Answer:
We need to solve this equation:
[tex]\frac{10}{4x}-3=2[/tex]
We pass -3 to the right summing:
[tex]\frac{10}{4x} = 2 + 3[/tex]
[tex]\frac{10}{4x}=5[/tex]
We pass the 4x that is dividing to the right multiplying:
[tex]10 = 5*4x[/tex]
[tex]10=20x[/tex]
We pass the 20 of the right to the left dividing:
[tex]\frac{10}{20}=x[/tex]
[tex]x=\frac{1}{2}[/tex]
Now, we know [tex]x=\frac{1}{2}[/tex], so we can verify:
[tex]\frac{10}{4*\frac{1}{2}}-3 = 2[/tex]
[tex]\frac{10}{2}-3=2[/tex]

WILL MARK BRAINLIEST An architect is drafting a scale drawing of a house for an upcoming project. The customer wants the front of the house to measure 60 feet long. The architect's sketch shows that the front of the house has a length of 15 inches. Determine the factor of dilation used by the architect as he created the scale drawing for his customer. In your final answer, include all of your calculations.
Answer:
The scale factor is 1/48
Step-by-step explanation:
First, we need to convert 60 feet to inches.
60 feet = 720 inches
Then, we divide 720 by 15
720/15= 48.
The scale factor is 1/48.
The scale factor of dilation is given by the proportion and A = 48
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
We can use the ratio of the lengths of the corresponding sides to find the scale factor or dilation factor used by the architect.
Let A be the factor of dilation used by the architect. Then we can set up the following proportion:
60 feet / A = 15 inches / 1
We can solve for x by cross-multiplying:
60 feet x 1 = A x 15 inches
A = (60 feet) / (15 inches)
We need to convert feet to inches to get the units to match:
A = (60 feet) / (15 inches) x (12 inches / 1 foot)
Simplifying, we get:
A = 720 / 15
A = 48
Hence , the architect used a scale factor of 48 when creating the scale drawing of the house

solve for h
can someone please answer and explain thank you <33
Answer: [tex]h=\frac{2A}{(a+b)}[/tex]
Step-by-step explanation:
To solve for h, we want to get h alone. We need to use our algebraic properties.
[tex]A=\frac{1}{2} h(a+b)[/tex] [multiply both sides by 2]
[tex]2A=h(a+b)[/tex] [divide both sides by (a+b)]
[tex]h=\frac{2A}{(a+b)}[/tex]
Now that we have h alone, we know that [tex]h=\frac{2A}{(a+b)}[/tex].

Solve for x. 3(2x - 2) = 21 + 3x
15 5 20 9
Answer:
x=9
Step-by-step explanation:
3(2x - 2) = 21 + 3x
Divide each side by 3
3/3(2x - 2) = 21/3 + 3x/3
2x-2 = 7+x
Subtract x from each side
2x-2-x = 7+x-x
x-2 = 7
Add 2 to each side
x-2+2 = 7+2
x = 9
A supermarket has 148 shrubs on their property, but they are having trouble mowing grass so they need to pay to have cut down shrubs each year until the property has less than 30 shrubs. If they can pay to have only three shrubs cut down this year, but six shrubs cut down every year after that, in how many years will they have less than 30 shrubs on their property?
Answer: 21 years
Step-by-step explanation: After the first year, it’s down by 3 so 145. For the next 20 years, you go down 6 shrubs a year. At year 20 it will be 31 shrubs so at year 21 it will be at 25 shrubs.
Answer:
21 years.
Step-by-step explanation:
All equations are written in bold so you can find them easier.The first thing we do is subtract the 3 shrubs from the first year from the total 148.
148 - 3 = 145
We then take 29 from 145, as the supermarket wants less than 30 shrubs on their property, so the maximum amount they want to keep is actually 29.
145 - 29 = 116
The supermarket can pay to have 6 shrubs cut down every year, excluding the first, so we need to do then is divide 116 by 6.
116 ÷ 6 = 19.333.
Because that equation leaves us with a decimal, we have to round up to get a whole number because the answer has to be in years, not years and months.
19.333 rounded up is 20.
So that's 20 years of paying for 6/per year. We have to add on the one year they only payed for 3 shrubs to be cut down, making the answer;
21 years.We can further confirm we have the right answer by doing;
6 × 20 = 120
145 - 120 = 25
Because we're going down in 6's, we know that 20 is the lowest amount of years it would take to get less than 30 shrubs, because 25 + 6 = 31.
The identification code on a bank card consists of 1 digit followed by 2 letters. The code must meet the following conditions: The digit must be odd. The letters A, E, I, O, and U cannot be used. Letters cannot be used more than once.
Answer:
For the code we have 3 selections.
The first selection is a digit that must be odd, so the options are {1, 3, 5, 7 ,9}
So we have 5 options.
The second selection is a letter from the set of all the letters (27) minus the set of the vowels (5)
So here we have 27 - 5 = 22 options
The third selection is also a letter from the previous set, but because each letter can be used only one time, and in the previous selection we already selected one of the letters, in this selection we have a letter less than in the previous selection.
Here we have 22 - 1 = 21 options.
The total number of combinations (of possible codes) is equal to the product of the number of options for each selection:
C = 5*22*21 = 2310.
There are 2310 different possible codes
What details can you determine about the dive from the coordinates of the point (5, −8)?
Answer:
(See explanation below for further details)
Step-by-step explanation:
A. What details can you determine about the dive from the coordinates of the point (5, -8)?
First component corresponds to time and second component to depth with respect to sea level. The diver is 8 feet below sea level at 5 seconds.
B. What is the average speed of the diver in the water? How can you tell from the graph?
The average speed of the diver ([tex]\bar v[/tex]), measured in feet per second, can be calculated by the following expression:
[tex]\bar v = \frac{x_{f}-x_{o}}{t_{f}-t_{o}}[/tex]
Where:
[tex]x_{o}[/tex], [tex]x_{f}[/tex] - Initial and final depth of diver, measured in feet.
[tex]t_{o}[/tex], [tex]t_{f}[/tex] - Initial and final instant, measured in seconds.
There are three different average speeds: (i) Descent ([tex]t = 1\,s[/tex] to [tex]t = 5\,s[/tex]), (ii) Ascent ([tex]t = 5\,s[/tex] to [tex]t = 9\,s[/tex]), (iii) Descent + Ascent ([tex]t = 1\,s[/tex] to [tex]t = 9\,s[/tex])
(i) Descent ([tex]t = 1\,s[/tex] to [tex]t = 5\,s[/tex])
[tex]x_{o} = 0\,ft[/tex] and [tex]x_{f} = -8\,ft[/tex]
[tex]\bar v_{i} = \frac{-8\,ft-0\,ft}{5\,s-1\,s}[/tex]
[tex]\bar v_{i} = -2\,\frac{ft}{s}[/tex]
(ii) Ascent ([tex]t = 5\,s[/tex] to [tex]t = 9\,s[/tex])
[tex]x_{o} = -8\,ft[/tex] and [tex]x_{f} = 0\,ft[/tex]
[tex]\bar v_{ii} = \frac{0\,ft-(-8\,ft)}{9\,s-5\,s}[/tex]
[tex]\bar v_{ii} = 2\,\frac{ft}{s}[/tex]
(iii) Descent + Ascent ([tex]t = 1\,s[/tex] to [tex]t = 9\,s[/tex])
[tex]x_{o} = 0\,ft[/tex] and [tex]x_{f} = 0\,ft[/tex]
[tex]\bar v_{iii} = \frac{0\,ft-0\,ft}{9\,s-1\,s}[/tex]
[tex]\bar v_{iii} = 0\,\frac{ft}{s}[/tex]
C. Which point on the graph shows the starting location of the diver?
The initial location is when [tex]t = 0\,s[/tex], which corresponds to the intercept of the line on y-axis.

Ms. Rangtonsmith make $25 dollars an hour. Her boss will be giving him a raise that is 1/5 of her current salary. How much money will Ms. Rangtonsmith be making AFTER he gets a raise?
Answer:
Ms. Rangtonsmith will get $30 after raise
Step-by-step explanation:
Current salary = $25
raise = 1/5 of current salary
substituting current salary with $25
raise in dollar value = 1/5 of $25 = 1/5 *$25 = $5
Thus, raise is $5
total salary after raise will be sum of current salary and raise
total salary after raise = $25 + $5 = $30
Thus, Ms. Rangtonsmith will get $30 after raise

A random sample of 100 cars was taken and data were recorded on the miles per gallon (mpg) in the city and on the highway. The mean city mpg was 28 with a standard deviation of 9.2. The mean highway mpg was 35 with a standard deviation of 8.6. The correlation coefficient between city mpg and highway mpg is 0.95. Although a scatterplot is not show, it has been determined that a linear equation is appropriate for the data. Determine the correct value of the slope for the linear model that predicts highway mpg based on city mpg and interpret it in context.
Answer:
0.89
Step-by-step explanation:
Nunber of samples = 100
City mpg :
Mean = 28
Standard deviation =9.2
Highway mpg:
Mean = 35
Standard deviation = 8.6
correlation Coefficient (r) between city mpg and highway mpg = 0.95.
The value of the slope of the regression line that predicts highway mpg based on city mpg can be obtained by:
(Standard deviation of highway mgp / standard deviation of city mpg) × correlation Coefficient
Slope = (8.6 / 9.2) × 0.95
Slope = (0.934782 × 0.95) = 0.8880
Slope = 0.89 ( two decimal place)

Answer:
(0, -5) and (4, 3)
Step-by-step explanation:
I assume you're looking for the coordinates of the intersections, if any.
Solve by substitution:
x² + (2x − 5)² = 25
x² + 4x² − 20x + 25 = 25
5x² − 20x = 0
5x (x − 4) = 0
x = 0 or 4
So the coordinates are (0, -5) and (4, 3).
