Answer
<h2>
4</h2>
Step-by-step explanation:
Given,
r = 10
Let's create an equation,
plugging the value of r
Multiply the numbers
Move 5s to L.H.S and change its sign
Similarly, Move 30 to R.H.S and change its sign.
Calculate
The difference sign ( - ) should be cancelled on both sides
Divide both sides of the equation by 5
Calculate
The value of s is 4.
Hope this helps..

6/7 (85%) is bigger than 3/4 (75%)
0=-16t^2 +64
0=-16(t^2 - 4)
0=-16(t-2)(t+2)
t=2 or - 2
