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!
In order to rationalize the denominator of each expression, we need to multiply the expression by the same radical in the denominator, this way we can remove the radical from the denominator.

Answer:
The lengths of all sides of the triangle will be 21 cm, 21 cm, and 21 cm
Step-by-step explanation:
Given that the perimeter of the triangle = 63 cm
And the length of one side = 21 cm
and one of the medians is perpendicular to one of its angle bisectors
Since triangle has 3 sides,
Median = 63 ÷ 3 = 21
Therefore each side length = 21 cm
If this is a problem about the Pythagorean theorem, maybe this helps! If the length of the ladder is 10 feet (C) and the base is 9 feet (B), you have to multiply each number by 2, add the total of both numbers and then round the number to the nearest hundreths ( use the radical button on your calculator) and there you have it , you will have the answer on your calculator. I hope this helps ;-)
