Let Mike sold M cars and Bill sold B cars.
Now both sold 640 cars in total, means M + B = 640,
also Mike sold 3 times as many as Bill, means M = 3*B. So our equations became,
M + B = 640, & M = 3*B, put value of M in terms of B.
3*B + B = 640, 4*B = 640,
B = 640/4, B = 160, as M = 3*B, M = 3*160 = 480.
So Mike sold 480 cars & Bill sold 160 cars.
Your equation should be 1.50x + 13 = 35.50
first, subtract 13 from both side leaving you with 1.50x = 22.50
now divide 1.50 from both sides
x = 15 (greatest number of rides)
Radius is 8
diameter is 16
curcumference is 50.24
Answer:
the answer is 15
Step-by-step explanation:

11 >

- 16
False, you should add 16 first to make the equation easier. If you multiplied by 4, you would have to multiply everything by 4, whereas by adding 16 first you only have to solve 27 · 4 to get a.
