Question

Claire correctly solved the proportion StartFraction x over 4 EndFraction = StartFraction 36 over 16 EndFraction for x by using cross products to get the equation 16 x = 144 and then dividing both sides by 16 to get x = 9. She showed that she can use cross products to solve the proportion because she gets the same answer if the solves it as shown.

Answer 1

c

Explanation:

I took the test and got it right

Answer 2

9

Explanation:

Given the expression:

`(x)/(4) = (36)/(16)`

We are to find the value of x.

Step 1:

Cross multiply

`(x)/(4) = (36)/(16)\\16 * x = 36 * 4\\16x = 144`

Step 2:

Find the value of x:

`(16x)/(16) = (144)/(16) \\x = 9`

Hence the value of x is 9
