9x+13=2x+48

Subtract 2x from both sides

7x+13=48
Subtract 13 from both sides

7x= 35

Mito bakes biscuits.He uses 1/4 cup of flour to coat the countertop and the rolling pin.He also uses 2 1/2 cups of flour for eac
Hoochie [10]

Answer:

<u>3  batches of biscuits.</u>

Step-by-step explanation:

For one batch of biscuits, Mito uses 1/4 cup of flour to coat the countertop and the rolling pin.He also uses 2 1/2 cups of flour for each batch of biscuits he bakes

When he uses 7 3/4 cups of flour

Let the number of batches = x

convert the given data to decimal:

2 1/2 = 2.5   and   1/4 = 0.25    and  7 3/4 = 7.75

So, the equation representing the problem is:

2.5 x + 0.25 = 7.75

Solve for x

2.5x = 7.75 - 0.25 = 7.5

x=7.5/2.5 = 75/25 = 3

<u>So, the number of batches of biscuits = 3 batches.</u>
