Answer

$\frac{75}{4}$

Work Step by Step

h=5 a=2 w=8 Rewrite the expression with the plugged in values substituting the variables: 4h-5a ÷ w 4(5) - 5(2) ÷ 8. Complete the order of operations. First, multiply the integers. 20-10 ÷8. Now divide 10 ÷8, which can also be put in fraction form,$\frac{10}{8}$. Simplify the fraction: $\frac{10}{8} = \frac{5}{4}$. Now add$ \frac{5}{4} + 20$. To solve the difference between the integers, change the 20 into an improper fraction to combine with $\frac{4}{4}$: 20= $\frac{80}{4}$. Combine the terms: $\frac{80}{4}−\frac{5}{4}=\frac{75}{4}$
