If I understand your question correctly then it's simple all you have to do is use the numbers in the place of the b and c so the question would be what is 8-7 which equals 1
Answer:
3770 mm.
Step-by-step explanation:
The diameter of of the wheels is 60mm, that means the radius is 30mm.
Now for one revolution of the wheels, they cover the distance of
on the ground.
For 20 revolutions, the distance covered will be 20 times this.
Thus
![Distance\: covered =188.5*20=\boxed{3770mm}](https://tex.z-dn.net/?f=Distance%5C%3A%20covered%20%3D188.5%2A20%3D%5Cboxed%7B3770mm%7D)
Which is our answer.
1/4 + 1/8= 3/8
Remember you need a common denominator so 4*2 is 8 and you multiply the numerator by 2 to get 2/8. Which makes the problem 2/8+1/8=3/8
Make two equations. Then solve. Let t and b represent the numbers of pages in the Tax Code and Bible, respectively.
t - b = 18,528 . . . . . tax code exceeds Bible by 18,528 pages
t + b = 21,472 . . . . .together, they total 21,472 pages
Add the two equations.
2t = 40,000
t = 20,000
The number of pages in the tax code is 20,000.
Let s = Car B's speed
Car B is 15 mph faster than A, therefore
(s - 15) = Car A's speed
Write a distance equation; dist = speed * time
2(s-15) = 1.5s
2s - 30 = 1.5s
2s - 1.5s = 30
.5s = 30
s = 60 mph is car B's speed
Confirm this find the distances, they should be equal
2 (60-15) = 90
1.5 (60) = 90
