The number of rotations for the new wheel will be 1,056 rotations
<h3>How to calculate the circumference of a wheel?</h3>
Let the initial circumference be 50 rotations (assumed)
If the number of rotations of the circumference of the tires were increased by 20%, then the new circumference will be:
Ne circumference = 1.2 * 50 = 60
number of rotations for the new wheel = 63360/60
number of rotations for the new wheel = 1,056 rotations
Hence the number of rotations for the new wheel will be 1,056 rotations

you combine like terms first.
for example: 2x=2+5
add up the two plus 5 so that will give you seven then you're going to divide 2 by 7 so that you isolate the x and you'll get your answer.
Answer:
l = P/2 -w
Step-by-step explanation:
P=2(l+w)
Divide each side by 2
P/2 = 2(l+w)/2
P/2 = l+w
Subtract w from each side
P/2 -w = l+w-w
P/2 -w =l
