Answer:
Width is 20cm
Step-by-step explanation:
Step one:
Given data
let the width be x
W= x
L= x+5
P= 90
Step two:
The expression for the perimeter is
P= 2L+2W
90= 2*x+2(x+5)
90= 2x+2x+10
collect like terms
90-10=4x
80= 4x
divide both sides by 4
x= 80/4
x= 20
Find the circumference of one wheel and then mult. that by 18:
C = 2*pi*r becomes C = 2*pi(1.14 m) = 2.28*pi m
Distance traveled: 18*C = 41.04*pi meters, or approx. 129 meters
Answer:
Step-by-step explanation:
10 - 4m + 7m = m - 10
Simply both sides:
10 + -4m + 7m = m + -10
Combine like terms:
( -4m + 7m) + (10) = m - 10
3m + 10 = m -10
3m + 10 = m - 10
Subtarct m from both sides:
3m + 10 - m = m - 10 - m
2m + 10 = -10
Subtract 10 from both sides:
2m + 10 - 10 = -10 - 10
2m = -20
Divide both sides by the 2:
2m/2 = -20/2
m = -10
<u>Answer =====> m = -10</u>
