arsen [322]

Answer: 1 cup of sugar

Step-by-step explanation:

A recipe for banana bread requires 3 cups of bananas for every 1 1/2 cups of sugar used.

Converting 1 1/2 cups of sugar to improper fraction becomes 3/2 cups of sugar.

If 3 cups of bananas is required for 3/2 cups of sugar,

x cups of bananas will require 1 cup of sugar

3x / 2 = 3

3x = 6

x = 6/3 = 2

Therefore,

2 cups of bananas will require 1 cup of sugar.

We are looking for the number of cups of sugar that would require 2 cups of bananas.

We already got the answer.

1 cup of sugar would be used if 2 cups of bananas are used.

Which one is the answer? Answer these two
kirill [66]

Answer

Expressions 4(x+5) and 5(x+4) are Equivalent

Expressions 5(2m+2) and 10m+10 are not equivalent

Step-by-step explanation:

Heres why,

4(x+5) and 5(x+4)

4 times x =4x, so multiply 4x by 5 which should give you 20.

and multiply 5 to x which would be 5x and multiply that to 4 which would be 20, they match up so they are Equivalent.

5(2m+2) and 10m+10

times 5 to 2m to get 10m and times 10m by 2 to get 20.

10m+10 = 1 which they are not equivalent
