Equation for Kelli's earning = 20x + 100
Equation for Karl's earning = 25x + 50
Now, 20x +100 = 25x +50
25x-20x = 100-50
5x = 50
x = 10
So, your answer is 10 hours.
Hope this helps!
Answer: the quotient will be equal to 23
The equation to calculate what divided by 23 equals 1 is as follows:
X/23 = 1
Where X is the answer. When we solve the equation by multiplying each side by 23, you get get:
X = 23
Therefore, the answer to what divided by 23 equals 1 is 23
so the quotient will be equal to 23

Answer:
5x + 13
Step-by-step explanation:
(3x + 9 ) + (2x + 4)
It's quite simple, we just have to add the parts that have x to each other and those that don't have x to each other
