Well if she earned the same amount per hour the hours can be added. 2.25 + 3.25 = 5.5 hours. To get the rate of earning per hour you would then divide the total made by the total time worked. 42/5.5 = $7.64 approximately.

We collect like terms
8x - 3x = 3 + 5 + 9
This is bcos if a (-) sign crosses the equals sign it becomes a (+), and if a (+) sign crosses the equals sign it becomes (-)
We the have
5x = 17
Divide both sides by 5
x = 17/5
x = 3.4
In vinegar with X and Y 5 when x 2.5 what is the value of y when x equals 20 I think the value is 0. 625
