Evaluate using order of operation and please show work​

Mathematics
1 answer:
Kamila [148]4 years ago
3 0

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

Explain the steps when solving 3(n+5) > or equal to 3n+8
Lynna [10]
Let me tell you....

This equation cannot be solved at all.

Why?

3(n+5)≥3n+8
3n+15 ≥ 3n+8
3n-3n ≥ 8-15
0 ≥ -7

Even though it make sense than 0 ≥ -7... But since 'n' disappeared, this means that this equation have no solution. To solve means to find the value of 'n' and if there is no 'n' since 3n-3n=0, there is no solutions.

This question is pretty much invalid.

Extra:
To tackle such inequality qns:
Step 1: Expand the brackets
Step 2: Move the term to one side of the equations
and constant to another side of the equation.
Step 3: Find the value of the term. Done.
