Answer:

C: [tex]\frac{7x}{4} + 5y[/tex]

Step-by-step explanation:

1. Realize that 12 inches is 1 feet and 36 inches is 1 yard.

2. Multiply it so that both are inches.

[tex]\frac{5y}{12} * 12 = 5y[/tex]

[tex]\frac{7x}{144} * 36 = \frac{7x}{4}[/tex]

3. Add together [tex]\frac{7x}{4} + 5y[/tex]

Answer:

C.

Step-by-step explanation:

I also recommend to just search these things on the internet. it would be much faster.

1 ft = 12 in

1 yd = 3 ft = 3×12 = 36 in

so, we need to multiply a given number of ft by 12, and a given number of yards by 36 to get the inches.

5y/12 × 12 = 5y

7x/144 × 36 = 7x/4

that is all there is to it.
