Answer:
Shelly's age is less than 21
Step-by-step explanation:
S+15 < 36
S < 21
sorry I answered wrongly
x^2-x-72 =0
find 2 numbers when multiplied = -72 and when added = 1
the zeros are 9 and -8
1 : 3 : 5
Given
$150 : $450 : $750 ( divide each part of the ratio by $150 )
= 1 : 3 : 5
16x+2=-7x-21
x = -1
So yeah
