Find the value of x that will make l and m 7x-7, 4x+14
1 answer:
<u><em>Answer:</em></u>
x = 7
<u><em>Explanation:</em></u>
<u>We are given that:</u>
l = 7x - 7
m = 4x + 14
<u>We want to have:</u>
l = m
<u>Therefore, we will simply equate the two equations and solve for x as follows:</u>
7x - 7 = 4x + 14
7x - 7 - 4x = 4x + 14 - 4x
3x - 7 = 14
3x - 7 + 7 = 14 + 7
3x = 21
x =
x = 7
Hope this helps :)

Answer:
The wheel have made revolutions.
Step-by-step explanation:
The total distance traveled during the race is
D = 4510km [(1000m)/(1km)] =
The radius (r1) of the smaller bicycle wheel is
r1 =
Than the larger wheel has a radius
r2 = 0.329 m + 0.012 m = 0.341 m
Over the same distance this wheel would make N2 revolutions
N2 =
