Question

Mac has 117 white and black

Answer 1

Answer:

The number of white horses is 52

Step-by-step explanation:

Let

x ----> the number of black horses

y ----> the number of white horses

we know that

$x+y=117$ ----> equation A

$\frac{x}{y}=\frac{5}{4}$

$x=\frac{5}{4}y$ ----> equation B

Substitute equation B in equation A and solve for y

$\frac{5}{4}y+y=117$

$\frac{9}{4}y=117$

$y=117(4)/9\\y=52$

therefore

The number of white horses is 52
