A student reads 65 pages per hour

1 answer:

6 0

195/3 = 65 pages per hour, but
322/5 = 64.4 pages per hour

No, this is not a proportional rel. If it were, the const. of prop. would be 65/pages per hour in every case.

Maggie’s brother is 12 years younger that three times her age . The sun of their ages is 44 . How old is Maggie

meriva

I'm not sure if this is right but you can set up an equation and solve to find Maggie's age:

Maggie's brother's age = b
Maggie's age = m

b = 12 - 3m
44 = 12-3m
12-3m = 44
-12 -12
-3m = 32
÷ 3 ÷3
m = 10.67

So this would be Maggie's age

I hope this helped :)
