Evaluate the expression when x = 5 and z= 7.
5z +x
Simplify your answer as much as possible.

12

Step-by-step explanation:

We are given the expression:

and asked to evaluate when x= 5 and z=7. Therefore, we must substitute 5 for x and z for 7.

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

First, evaluate the exponent.

(5)²= 5*5= 25

Next, multiply 5 and 7.

5*7=35

Next, add 35 and 25.

25+25=60

Finally, divide 60 by 5.

The expression (5z+x²)/x when x=5 and z=7 is 12.

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
