Could someone explain what each step is and what each step is called? only 15 and 17 and you

15. 2x-5=-20

2x=-15; Add positive 5 on both sides to isolate x.

x=; Divide 2 on both sides to find the value of x.

17. =-9

9x=-36; Multiply positive 4 on both sides of the equation.

x==-4; Divide 9 on both sides of the equation to find the value of x.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

$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.
