Answer:

Step-by-step explanation:
Given data
Height of building= 30ft
We are told that after the ball landed it bounced 85% the height
let the new height be y
So the expression for the new height for x number of bounces is

Sandy's cost equation is y = 5x + 10 where y = cost and x = number of children.
Kimmi's cost equation is y = 25 where y = cost.
The fees are the same when x = 3 in other words when Sandy babysits 3 children.
That is found by solving 5x + 10 = 25 for x.
Subtract 10 from each side: 5x = 15
Divide by 5 on both sides: x = 3
You can set this up as 5(3+4)....then, distribute by multiplying the terms in parentheses by 5. This gives you 15+20, which equals 35.
3/4 times 16/9 is equal to 1 1/3.
