Answer:
112
Step-by-step explanation:
Since 7 goes into 7 put it down and subtract it’s 0
drop down 8 and only 7 goes into it (now you have 11 at the moment)
you have 1 remaining, drop down the 9, 7 goes in 15 twice, (so it’s 112)
with remainder of 5
It’s 5 since you’d use Pythagorean theorem

Brainly says my answer is too short so I have to add extra text here
![x=63](https://tex.z-dn.net/?f=x%3D63)
which is Marcella's age
![\frac{1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20)
of 63 is 21 ⇔ 63÷3=21
![2+21=23](https://tex.z-dn.net/?f=2%2B21%3D23)
which is Justins age
![2(23)-4=42](https://tex.z-dn.net/?f=2%2823%29-4%3D42)
Marcella's age⇒63
Justin's age⇒23
Aimee's age⇒42
Note: I was trying to find a better way to do this but I couldn't figure it out in the top of my head so I'm sorry for the long response
