Answer:
Step-by-step explanation:
12x - 9 = 8x + 7
4x - 9 = 7
4x = 16
x = 4
solution is C
10^ 7 = 10,000,000 which is 10 million
10^ 8 is 100 million
10^8 is closer, it is only 130 million away while 10^7 is 220 million away

The Anwser to 29-40 is -11
The car moved 175.84 cm in one revolution
The car has moved 17584 cm in 100 revolutions
<em><u>Solution:</u></em>
Given that car wheel is 56 cm in diameter
diameter = 56 cm
To find: distance traveled in one revolution of wheel
Usually wheel is of circular shape
one revolution of wheel = circumference of circle
<em><u>The circumference of circle is given as:</u></em>

We know that,
diameter = 2(radius)

<em><u>So the circumference becomes:</u></em>

substitute
= 3.14 and d = 56 cm

Thus the car moved 175.84 cm in one revolution
<em><u>B. How far does it go in 100 revolutions</u></em>
Distance covered in 100 revolutions = 100 x Distance covered in 1 revolution

Thus the car has moved 17584 cm in 100 revolutions
