Question

Evaluate using order of operation and please show work​

Answer 1

Answer:

10

Step-by-step explanation:

Given expression:

                   20 - $\frac{15 + 3(5)^{2} }{5^{2} - 4^{2} }$

     To solve this problem, we use the order of operation:

P - Parentheses

E - exponents

M - multiplication

D - division

A - Addition

S - Subtraction

  Now solve the parentheses first;

     =   20 - $\frac{15 + 3x 25}{5^{2} - 4^{2} }$

     =    20 - $\frac{15 + 75}{5^{2} - 4^{2} }$

     Now solve the exponents:

    = 20 - $\frac{15 + 75}{25 - 16}$

    Now solve the division:

     = 20 - $\frac{90}{9}$

     = 20 - 10

     = 10
