18/2= 9
45/5= 9
9 x 4 = 36
Answer:
AC = 36
Step-by-step explanation:
since these triangles are similar, we can use the triangle similitary theorem. This means that the sides are proportional to each other.
ef/bc = 5/45 (1/9) = ed/ba = 2/18 (1/9)
we can see the sides are in a ratio of 1:9, and plug it in the proportion
df/ac = 1/9
4/ac = 1/9
cross multiply and we get that ac = 36

Deborah spent $70 on food and clothes. She spent $26 more on clothes than on food. On your worksheet, solve the question and write your answer below. How much did she spend on food and how much did she spend on clothes?
Answers
Answer:
She spent $22 on food, and $48 on clothes.
Step-by-step explanation:
Let's define the variables:
C = amount of money that Deborah spent on clothes
F = amount of money that Deborah spent on food.
We know that she spent in total $70, then we have the equation:
F + C = $70
And we know that she spent $26 more on clothes than on food, then we have the equation:
C = F + $26
This means that we have a system of equations:
F + C = $70
C = F + $26
To solve these type of systems, we usually start by isolating one variable in one of the equations. Here we can see that C is already isolated in the second equation.
Now we can replace it in the first equation.
F + (F + $26) = $70
Now we can solve this for F.
2*F + $26 = $70
2*F = $70 - $26 = $44
F = $44/2 = $22
So she spent $22 on food.
Now we can use the equation:
C = F + $26
To find how much she spent on clothes, where we need to replace F by the value we found.
C = $22 + $26 = $48
She spent $48 on clothes.

The width of a rectangle is 32 inches. The width of the rectangle decreased by 8 inches and its length also changed. The area of the rectangle remains the same, 1,440 square inches. What is the new length of the rectangle?
Answers
Answer:
60 in
Step-by-step explanation:
Area = length x width
Area is constant at 1440 in^2
For first rectangle: W1 and L1
For second rectangle: W2 and L2
W1 = 32 in
W2 = W1 - 8 in = 24 in
1440 in^2 = L1 x 32 in = L2 x 24 in
L1 = 45 in
L2 = 60 in

Leyan bought 2 3/4 pounds of apples for $1.32 per pound, 1 1/2 pounds of peaches for $1.20 per pound, and some tomatoes, all from a grocery store. The total cost of his purchase was $9.63. . How much money did Leyan spend on tomatoes?
Answers
Explanation: First, we need to know how much was spent on apples and peaches.
The equation for the amount spent on apples is $1.32/1 lbs=$x=(2 3/4 lbs), where 2 3/4 * 1.32=$3.63
As for peaches, we have $1.20/1 lb=$x/(1.5 lbs), where 1.5 * 1.20=$1.80
Finally, $9.63-(3.63+1.80)=$4.20

Answers
Y= -48
Explanation:
Since we know that 3x-24 is equal to y, we can plug that in for y in the equation 5x-y=8. That would look like 5x-(3x-24)=8. Distribute the -1 and you will get 5x-3x+24=8. Subtract 24 from both sides and get 2x=-16. Divide both by 2 and get x=-8. Than plug in -8 for y in one of the equations to get the y. You will get -48.

Please help me what is a NOW a/4 − 5/6 = −1/2
Answers
Answer:
Step-by-step explanation:
Change the denominator of the 1/2 to sixths. Multiply the top and bottom by 3 to get 3/6
[tex]\frac{a}{4}-\frac{5}{6}=-\frac{3}{6} \\[/tex]
Add 5/6 to both sides and simplify
[tex]\frac{a}{4} =\frac{1}{3}[/tex]
Multiply both sides by 4 to get
a=4/3
A/4 -1 x 5/6 = -1/2
A/ 4 - 5/6 =-1/2
Add 5/6 to both sides of the equation
A/4 -5/6 =1/2
A/4 -5/6+5/6 =-1/2 +5/6
Simplify
Add the numbers
A/4 =1/3
Multiply all terms by the same value to eliminate fraction denominators
A/4 = 1/3
4x a/4 =4x1/3
Simplify
Cancel multiplied terms that are in the denominator
Multiply the numbers
A=4/3
Solution
A=4/3

Answer:
C. Every year the number of subscribers is estimated to increase by 8% over the
number of subscribers the year before.
Step-by-step explanation:
Using the formula :
S = 20,000 (1 + 0.08)^y to estimate ;
S = number of subscribers ; y = years
The expression : (1 + 0.08)^y
0.08 = 0.08 * 100% = 8%
(1 + 0.08)^y represents a continous growth or increase in the number of subcsribers by 8% over the number of subscribers the preceeding year

A study indicated that residents of manchester wasted 2695 gallons of water this tear. That is 50% less than last year . How many gallons of water did the city's residents waste last year?
Answers
Answer:
5390 gallons of water was wasted by the city's residents last year.
Step-by-step explanation:
Let [tex]x[/tex] denotes gallons of water wasted by the city's residents last year.
Gallons of water wasted by the city's residents this year = 2695 gallons
This is 50% less than last year.
Therefore,
[tex]x-\frac{50}{100}x=2695\\\\\frac{50}{100}x=2695\\\\\frac{x}{2} =2695\\\\x=2(2695)[/tex]
[tex]x=5390[/tex] gallons
So, 5390 gallons of water was wasted by the city's residents last year.
