Priya has a recipe for banana bread. She uses 7 ½ cups of flour to make 3 loaves of banana bread. Andre will follow the same rec

Mnenie [13.5K]

Answer:

Option B)

$b = \dfrac{2}{5}f$

Step-by-step explanation:

We are given the following in the question:

Priya uses $7\frac{1}{2}$ cups of flour to make 3 loaves of banana bread.

Thus, we can write the ration of bread to amount of flour used as:

$\text{Ratio} = \dfrac{3}{7\frac{1}{2}} = \dfrac{3}{\frac{15}{2}} = \dfrac{6}{15}$

Now, b loaves of banana bread using f cups of flour.

This measurement will follow the same ratio.

Thus, we can write:

$\dfrac{b}{f} = \dfrac{6}{15}\\\\b = \dfrac{2}{5}f$

Thus, the correct answer is

Option B)

$b = \dfrac{2}{5}f$

Solve: 3(5x - 8) = 6x + 39

soldier1979 [14.2K]

Steps to solve:

3(5x - 8) = 6x + 39

~Distribute left side

15x - 24 = 6x + 39

~Add 24 to both sides

15x = 6x + 63

~Subtract 6x to both sides

9x = 63

~Divide 9 to both sides

x = 7

Best of Luck!
