The expression that is equivalent to 2(m - 5) + 6
is 2m - 4.
The given algebraic equation consists of
numbers, arithmetic operations, and variables.
The first thing to do is to open the brackets.
After that, we will sum up or subtract the like

A tire from Karens car is shown below Which is closest to the distance traveled, in feet, after 3 full rotations of the tire? use pi= 22/7

Answers

Answer:

264 inches

Step-by-step explanation:

Circumference = pi x diameter

28 x 22/7 = 88 (in)

88 x 3  = 264 (in)

The closest distance traveled by Karen's car is, 18.86 feet.

What is Circle?

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We know that;

One rotation of the tire is equal to the circumference of the tire.

And, The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd

where, π = 22/7

d = diameter

Here, The size of one revolution = 2 x 22/7

                                                   = 44/7 feet

Hence, The distance covered in one rotation of the tire is 44/7 feet

So, The distance covered in 3 rotations = (44/7) x 3

                                                             = 18.86 feet
