2 * M = X
M = to minutes
x = to how many tables washes
1) a. x = number of cars
b. x - 12
2) a. x = number of packages
b. 16 + 1/2x
3) a. x = number of coins
b. 1/2x - 6
4) 17 + x = 78
Subtract 17 from each side.
x = 61
5) x - 33 = 78
Add 33 to each side.
x = 111
6) x * 84 = 327.6
Divide each side by 84
x = 3.9
7) 1333/8.6 = 155
The speed was 155mph.
8) 2475/110 = 22.5
The trip took 22 and a half hours. (Or "The trip took 22.5 hours."
You would divide the 2/3 by 4 which would be 1.6 recurring and then put that back into a fraction which would be 1/6. I'm not sure if his is correct but this what is learnt ♡♡chyna
<h3>
Answer: x = 3</h3>
To get that answer, we replace y with 8 and then isolate x.
5x-7 = y
5x-7 = 8
5x = 8+7
5x = 15
x = 15/5
x = 3
Answer: 91 coins
9 x 25 = 2.25 dollars
3 x 10 = 30 cents
