I NEED THIS ANSWER BY TONIGHT!!!! How many gallons of a 90% antifreeze solution must be mixed with 100 gallons of 20% antifreeze to get a mixture that is 80% antifreeze? Use the six-step method.
Answers
Answer:
Solution : 600 gallons
Step-by-step explanation:
Let's say that x is the gallons of 90% antifreeze solution. Let's start by converting each percent to decimal form.
90% = 0.9
20% = 0.2
80% = 0.8
Knowing that we have the following set up,
0.9(x) + 0.2(100) = 0.8(x + 100) ⇒ 0.8 is associated with " x + 100 " as it is a mixture of the gallons of the 90% antifreeze solution, and the gallons of the 20% antifreeze solution
We can solve for x in this equation, and receive our solution. This is represented by the following attachment. It proves that there are 600 gallons of the 90% antifreeze solution.
Find an equation of the line that passes through the given point and has the indicated slope m.
Answers
Answer:
y = [tex]\frac{4}{5}[/tex] x + 2
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 )
Here m = [tex]\frac{4}{5}[/tex] , thus
y = [tex]\frac{4}{5}[/tex] x + c ← is the partial equation
To find c substitute (- 5, - 2) into the partial equation
- 2 = - 4 + c ⇒ c = - 2 + 4 = 2
y = [tex]\frac{4}{5}[/tex] x + 2 ← equation of line in slope- intercept form

the perimeter of a rectangle is 44 cm.if its length is increased by 4 cm and breadth is increased by 2 cm its area is increased by 72 sqcm. find the dimensions of the rectangle
Answers
Answer:
11 cm, 11 cm
Step-by-step explanation:
Let the length and width of the rectangle be x cm and y cm respectively.
Therefore,
Perimeter of rectangle = 44 cm
2(x + y) = 44
x + y = 44/2
x + y = 22...... (1)
Area of rectangle = xy
When length is increased by 4 cm and breadth is increased by 2 cm.
New length = (x + 4) cm
New width = (y + 2) cm
New area of rectangle = original area + 72.. (given)
Therefore,
(x + 4) (y + 2) = xy + 72
xy + 2x + 4y + 8 = xy + 72
2x + 4y = 72 - 8
2x + 4y = 66
2(x + 2y) = 66
x + 2y = 66/2
x + 2y = 33.... (2)
Subtracting equation (1) from equation (2)
x + 2y - (x + y) = 33 - 22
x + 2y - x - y = 11
y = 11
Substituting y = 11 in equation (1)
x + 11 = 22
x = 22 - 11
x = 11
Thus, the dimensions of the rectangle are 11 cm and 11 cm.

If Mary and Tom put their money together they have £36. If Mary's money were halved and Tom's money doubled they would have £42. How much does each of them have? If you're answering, could you please show working out, thanks so much.
Answers
Answer:
Mary has £20 and Tom has £16
Step-by-step explanation:
Represent their current respective money amounts by m and t.
Then m + t = £36, but also m/2 + 2t = £42.
Multiplying the second equation by 2 removes the fraction:
m + 4t = £84
and multiplying this by -1 results in
-m - 4t = -£84, which can now be added to the first equation m + t = £36:
-m - 4t = -£84
+m + t = £36
---------------------
-3t = -£48
We have successfully eliminated m. To solve this last result for t, divide both sides by -3, obtaining t = £16
Since m + t = £36 and t = £16, m must be £20.
Mary has £20 and Tom has £16

inverse of g(x)=2x -8
Answers
Answer:
The inverse is 1/2x +4
Step-by-step explanation:
g(x)=2x -8
y = 2x-8
Exchange x and y
x = 2y-8
Solve for y
x+8 = 2y-8+8
x+8 = 2y
Divide by 2
1/2 x + 8/2 = 2y/2
1/2x +4 = y
The inverse is 1/2x +4
Answer:
y = 1/2x + 4
Step-by-step explanation:
The first equation is y = 2x - 8
switch out y for x
x = 2y - 8
add 8 to both sides
2y = x + 8
divide by 2 on each side
y = 1/2x + 4

2.1 subtracting a fraction from a whole
rewrite the whole as a fraction using 9 as the denominator
x=x/1=x•9/9
evaluate fraction: the fraction those granted looks different but has the same value as the whole.
common denominator: The equivalent fraction in the other fraction fault in the calculation share the denominator.
2.2 adding up The two equivalent fractions
Add the two equivalent fractions which now have a common denominator
combine the numberators together, put the sum of difference over the common denominator then reduce to the lowest terms as possible:
x•9-(7)/9 = 9x-7/9
y-(9x-7)/9=0
then adding up to the equivalent fractions
9y-9x+7/9=0
now to get rid of the denominator, multiple both sides
9y-9x+7/9•9=0•9
9y-9x+7=0
now this is the formula
Y tells us how far up the line goes
X tells us how far along
M is the slope
B is the Y-intercept
the X and Y intercepts and the slope are called the line properties. we shall now graph line 9y-9x+7=0
ANSWER IS
Slope=1.000
Y-intercept=-7/9
X-intercept=7/9

3х – 13 = 23
Please give an explanation to the answer
Answers
Answer:
x = 12
Step-by-step explanation:
3x - 13 = 23
Bring non-variable numbers to other side:
3x = 36
Divide both sides by 3:
x = 12
Answer:
x = 12
Step-by-step explanation:
This equation is very easy to solve.
3x - 13 = 23 Add 13 to both sides of the equation.
3x = 36 Divide by 3 on both sides of the equation.
x = 12
Then, check your answer by substituting the solved value.
3(12) - 13 = 23
36 - 13 = 23
23 = 23
Therefore, x = 12 is the solution to the equation.

Answers
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 2
Answer:
x=2
Step-by-step explanation:
7/8(-32)-7/8(48x)+36=2/3(-33x)-2/3(18)-10x
= -224/8-336x/8+36
=-66x/3-36/3-10x.
Simplifying the fractions
-28-42x+36=-22x-12-10x.
Combining like terms
-42x+8=-32x-12.
Add 32x to both sides:
-42x+8+32x=-32x-12+32x
-10x+8=-12.
Subtract 8 from both sides:
-10x+8-8=-12-8
-10x=-20.
Divide both sides by -10:
-10x/-10 = -20/-10

The price of a share of stock for Nike at the beginning of the week was $24.75. Over the next five days, the share of stock gained $2.50 on Monday, lost $3.25 on Tuesday, lost $0.75 on Wednesday, gained $1.25 on Thursday, and gained $4.75 on Friday. What was the price of the share of stock at the end of Friday? A. $37.25 B. $29.25 C. $12.25 D. $22.50 What is the Answer?
Answers
Answer: B. $29.25
Step-by-step explanation:
In integers loss is represented by negative integers whereas profit is represented by positive numbers.Given, Beginning price = $24.75
Over the next 5 days,
On Monday, gain of $2.50 represented by + $2.50.
On Tuesday, loss of $3.25 represented by - $3.25 .
On Wednesday, loss of $0.75 represented by - $0.75.
On Thursday, gain of $1.25 represented by + $1.25.
On Friday, gain of $4.75 represented by + $4.75.
Price of the share of stock at the end of Friday = (Beginning price)+ ( + $2.50 - $3.25- $0.75+ $1.25+ $4.75)
= $( 24.75 + 2.50 -3.25 -0.75 +1.25 +4.75)
= $29.25
Hence, the correct option is B. $29.25.
