Question

!!PLEASEE HELLPP!!

It’s the second and third one!!

Answer 1

2.) s = 32

3.) y=10, x=80

Explanation:

3.) x=y=90

10+80=90

80/8=10, so 80 is 10 times bigger

Answer 2

For 2, because Sophia read 4 times as many books as her brother, I think you just multiply 8 by 4 which is 32.

For number 3:

8y+y=90
9y= 90
y=10

Because x is 8 times larger than y: 10x8=80

(SO SORRY IF I AM WRONG BTW)
