For every 140 feet that Kelly rides on her bicycle, the wheels turn 20 times. About
1 answer:
To cover 5 miles the wheel covers 3771.42 (approx) turns.
Step-by-step explanation:
Given,
In 20 times turns wheel covers 140 feet.
1 mile = 5280 feet
To find the number of times wheels turns to cover 5 miles.
We will apply unitary method.
Now,
5 miles = 5×5280 feet = 26400 feet
140 feet covers in 20 turns
1 feet covers turns
26400 feet covers in ×26400 turns
= 3771.42 (approx) turns

Step-by-step explanation:
let the number be x , then :
six added to twice the sum of a number and four means :
one half of the difference of three and the number means :
combining the two , we have
=
First, we'll find the slope of the new line. The first line has a slope of . Take the negative reciprocal of this (Flip the numerator and denominator, then multiply by
) to get
for the new slope.
Then, we'll use the point-slope form to make the new equation, where is the slope and
is a point on the line:
