Answer:
Not sure what the question is but if you're looking for who runs the most in a second I can give you that
Emily: 11 feet per second
Will: 9.66 feet per second
Stephanie: 13.27 feet per second
Liz: 8.98 feet per second
Based off this info, Stephanie runs the fastest per second
K is the amount that the function will go up or down.
It is typically the y intercept
i don’t know for sure but i just figured it out....
You have to divide 48 by 4. How many times does 4 go into 48.....................12 times.
The rate charged per hour by each mechanic was: x = 75 $ / hr and y = 115 $ / hr.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given;
The first mechanic worked for 20 hours, and the second mechanic worked for 15 hours.
Together they charged a total of $3225.
For this case we have the following variables:
x be the amount of $ / hr that the mechanic obtains 1.
y be the amount of $ / hr obtained by mechanic 2.
An equation to express this would be:
x + y = 190
20x + 15y = 3225
Solving the system of equations we have:
20x + 15(190 -x) = 3225
20x + 2850 - 15x = 3225
5x = 375
x = 75
simililary
y = 190 - x
y = 115
Hence, the rate charged per hour by each mechanic was:
x = 75 $ / hr
y = 115 $ / hr
