Bill can wash a car in 6 minutes Joe can wash the same car in 8 minutes How much time would it take for them to wash that same car working together
In 1 minute bill washes 1/6 of a car and Joe washes 1/8 of a car. 1/6 + 1/8 = 14/48. A whole care = 48/48. Therefore you should divide 48 by 14 to get 3.429. However since this is in minutes you need to find how much seconds 0.429 of 1 minute is. 0.429 x 60 = 26 seconds (rounded). Add that to the original three minutes and you have 3 minutes 26 sec to wash the entire car working together.

Solve for x 5 plus 4x equals 3
Simplify the algebraic expression 2x-3y-7y plus 4x-5 and evaluate it for x equals 10 and y equals 4
2x - 3y -7y + 4x - 5 = 6x - 10y - 5 and (6 x 10) - (10 x 4 ) - 5
= 60 - 40 - 5 = 15

Ben thinks of a number he adds half of the number to a quarter of the number The result is 60 what is the number Ben first thought of
So 60 is 3/4 of his number. It must have been close to 80...
What number can be decreased by 6 and the result doubled to get 24
The number is 18.
Let x be the number, The equation is
(x-6) * 2 = 24
2(x-6) = 24
2x -12 = 24
2x = 24 + 12
2x = 36
x = 18
What is the simplification form of 2x plus 3-10
Simplist form of 2x plus 3-10 is 2x-7.
3x plus 8 equals 20-3x what is x
3x + 8 = 20 - 3x
6x = 12
x = 2
Is an advantage to using equations
What is 45-5x equals 5x plus 55
45-5x = 5x+55
-5x-5x = 55-45
-10x = 10
x = -1
When you solve for x what is x plus 13 equals 22
X +13 equals 22, X equals nine
What is the solution to x 14 8
Assume that the expression is:
x + 14 = 8
Then subtract both sides by 14 to get:
x + 14 - 14 = 8 - 14
x = -6
If x = 14 + 8, then x = 22.
