Answer:
4x + 10 > 3x + 14
x > 4
Step-by-step explanation:
Use the given values for length and width in the formula for perimeter of a rectangle. You will be able to find the perimeter of rectangles A and B.
A = 2(l + w)
A = 2(x + 5 + x)
A = 2(2x + 5)
A = 4x + 10
B = 2(l + w)
B = 2(x + 7 + x/2)
B = 2(3x/2 + 7)
B = 3x + 14
The perimeter of rectangle A is larger than that of rectangle B.
A > B
4x + 10 > 3x + 14
(4x + 10) - 3x > (3x + 14) - 3x
x + 10 > 14
(x + 10) - 10 > 14 - 10
x > 4

Steve had 48 chocolates but decided to give 8 chocolates to each of his coworkers. How many chocolates does Steve have left? Write your answer as an expression.
Answer:
y = 48 - (8x)
Step-by-step explanation:
x = unknown number of coworkers
y = number of chocolates left over
y = 48 - (8x)
Example: If you were to plug in the number 5 for x:
y = 48 - (8(5))
y = 48 - 40
y = 8
The answer is 48-8f

9) The speed limit on the freeway is 65 miles per hour. a) What is this speed in kilometers per minute?
b) If you drive for 3.5 hours at the speed limit? How many kilometers have you travelled?
Answer: Answer is in the steps
Step-by-step explanation:
A) First convert 65 miles to kilometers
65 miles to kilometers is 104.607
Convert 1 hour to minute and that will be 60 minutes because 60 minutes makes and hour.
Now divide the kilometers by the number of minutes
104.607 / 60 = 1.74345
The speed will be 1.74345 kilometers per minute.
B) Convert 3.5 hours to minutes.
3.5 hours is the same as 210 minutes
Now multiply it by 1.74345 to determine how many kilometers you have traveled.
1.74345 * 210 = 366.1245
You will travel 366.1245 kilometers in 3.5 hours.

Olivia counted the number of ladybugs on each plant in her garden, then made the graph below.
If ten ladybug fly from the lettuce to the alfalfa, which 2 kinds of plants will have the same number of ladybugs?
Choose 2 answers:
A) Roses
B) Lettuce
C) Alfalfa
D) Grape vines
Answer:
A) Roses , C) Alfalfa
Step-by-step explanation:
Each ladybug symbol = 5 ladybugs
Roses: 35 ladybugs
Lettuce: 15 ladybugs
Alfalfa: 25 ladybugs
Grape vines: 10 ladybugs
10 ladybugs go from lettuce to alfalfa. You end up with:
Roses: 35 ladybugs
Lettuce: 5 ladybugs
Alfalfa: 35 ladybugs
Grape vines: 10 ladybugs
Roses and alfalfa end up with 35 ladybugs each.
Answer: A) Roses , C) Alfalfa

Alexia ran three laps around her neighborhood. Each lap is 1 and StartFraction 3 over 8 EndFraction miles. Which is the best estimate of the number of miles that Alexia ran?
Answer:
4 and 1/8
Step-by-step explanation:
1 and 3/8 is equivalent to 11/8 which is one lap. If she ran 3 laps, you would multiply 11/8 by 3 which would get you 33/8- which is equivalent to 4 and 1/8.

y/2 - 1/5 = 2 - y/3
Answer:
y=2 16/25
in other words, two and sixteen twenty-fifths
Step-by-step explanation:
y/2-1/5=2-y/3
Move the variables to one side and constants to the other
y/2+y/3=2+1/5
Multiply y/2 by 3/3 and y/3 by 2/2 so that they have a common denominator
3y/6+2y/6=2 1/5
5y/6=11/5
Cross multiply
66=25y
y=66/25
y=2 16/25

What is the slope of the equation y – 3 = –4(x – 5)?e of the equation y – 3 = –4(x – 5)?
Answer:
The slope of the equation y-3=-4(x-5) is -4.
Step-by-step explanation:
This equation is written in point-slope form: y-y₁=m(x-x₁), where "m" is the slope or the equations. In the equation y-3=-4(x-5), the -4 stands in the "m", or slope, spot, so the sope of this equation is -4.
Slope of the equation is equals to -4.
What is slope?
" Slope is defined as the ratio of the change in y-coordinates to the x-coordinates. It is also known as inclined plane."
General equation of line
y = m x + c ____(1)
'm' = slope of the line
'c' = y - intercept
According to the question,
Given equation,
[tex]y-3 = -4(x-5)[/tex]
Open the brackets of the equation we get,
[tex]y-3 = -4x+20[/tex]
Add 3 both the sides of the equation we get,
[tex]y = -4x+23[/tex] ______(2)
Compare equation (1) and (2) to get the slope we have,
Slope 'm' = -4
y-intercept = 23
Hence, slope of the equation is equals to -4.

Solve. -1/2+(3/4x4/9)=
Answer:
-1/6
Step-by-step explanation:
- 1/2 + 3/4 x 4/9 = -1/2 + 3(4) / 4(9) = -1/2 + 12 / 36 = -1/ 2 + 1 / 3 = -3/6 + 2/6 = -1/6
The solution for the given expression [tex]-\frac{1}{2} +(\frac{3}{4} \times \frac{4}{9} )[/tex] after simplifying the expression is [tex]-\frac{1}{6}[/tex].
Given an expression:
[tex]-\frac{1}{2} +(\frac{3}{4} \times \frac{4}{9} )[/tex]
It is required to find the value of the expression after simplifying the expression.
Since there is more than one operation used in this expression, the rule of BODMAS has to be used.
The expression in brackets has to be solved first, which is [tex]\frac{3}{4} \times \frac{4}{9}[/tex].
Here, the numerator of the first fraction and the denominator of the second fraction is 4. So, it can be canceled.
So, this can be simplified as:
[tex]\frac{3}{4} \times \frac{4}{9} =\frac{3}{9}[/tex]
[tex]=\frac{1}{3}[/tex]
The whole expression thus is [tex]-\frac{1}{2} +\frac{1}{3}[/tex].
Make the denominators equal.
[tex]-\frac{1}{2} +\frac{1}{3} =-\frac{3}{6} +\frac{2}{6}[/tex]
[tex]=-\frac{1}{6}[/tex]
Hence, the value is [tex]-\frac{1}{6}[/tex].

Answer:
[tex]\bold{\angle NLM = 10^\circ}[/tex]
Step-by-step explanation:
Given a ΔLMN.
Line LN is extended to point O.
such that:
[tex]\text{m}\angle MNO = (5x-13)^{\circ}[/tex]
[tex]\text{m}\angle NLM = (x-4)^{\circ}[/tex] and

To find:
[tex]\text{m}\angle NLM=?[/tex]
Solution:
Kindly refer to the attached image for the given triangle and dimensions of angles.
Let us recall the external angle property of a triangle:
The external angle of a triangle is equal to the sum of two opposite internal angles.
i.e.
[tex]\angle MNO = \angle NLM + \angle LMN\\\Rightarrow 5x-13 = x-4+2x+19\\\Rightarrow 5x-13 = 3x+15\\\Rightarrow 5x-3x = 13+15\\\Rightarrow 2x=28\\\Rightarrow x =14[/tex]
Putting the value of [tex]x[/tex] in [tex]\angle NLM[/tex].
[tex]\angle NLM=14-4 \\\Rightarrow \bold{\angle NLM = 10^\circ}[/tex]

Answer:
y = - 2x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (1,1) ← 2 points on the line
m = [tex]\frac{1-3}{1-0}[/tex] = - 2
The line crosses the y- axis at (0, 3) ⇒ c = 3
y = - 2x + 3 ← equation of line
