Ray has $25 to spend and used $18 to buy a new DVD. Which integer best represents the situation of spending $18

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

first 15 divide by 2 = 7.5

100 divided by 7.5 is 13.

15 / 2 = 7.5

100 / 7.5 = 13.

-3(b-8)-5=9(b+2)+1

distribute

-3b+24-5=9b+18+1

add/ subtract

-3b+20=9b+19

20-19= 1

-3b+1=9b

9b+3b= 12b

1=12b

1 divided by 12 = 1/12

answer: 1/12 = b
