Answer:
The answer is "Option a".
Step-by-step explannation:
that's why the choice a is correct.
So, the first thing you should do is break it down. First how much space can she have, and how many hotdogs and hamburgers would she have know the amount of space. Then you would find the amount of money she would make if she sold the food, and how much she would spend for inventory. Hope this helps!
Answer:
labor fee: $15.15, quart of oil: $1.25
Step-by-step explanation:
You solve this by setting up two equations, one for each car.
First we have to define what variables we need and what they mean.
To be solvable, you need as many equations as you have variables.
Let's call the labor fee x and the cost of oil per quart y.
This means we'll be needing two equations to have any chance of solving this. Since we have one equation per car, this looks promising!
Car 1: x + 5y = 21.4
Car 2: x + 7y = 23.9
To solve these, you combine them into one equation by eliminating one variable:
Rewriting the first: x = 21.4 - 5y
So, we can substitute 21.4 - 5y for x in the second. Then we have an equation with only y:
21.4 - 5y + 7y = 23.9
2y = 23.9-21.4 = 2.5
y = 1.25
Plugging this value back into the rewritten first gives us the labour fee:
x = 21.4 - 5*1.25 = 15.15
Answer:
Step-by-step explanation:
She did not keep the order of the points the same in the numerator and the denominator.
I hope this helps!
...............................................................................................................................................
slope is y2-y1/x2-x1
if this was set up correctly it would be 17 - 1/18 - 14
The student simply switched the places of the y change calculation.

The answer is D. She should have used 8-1 as the denominator since she used 17-14 as the numerator.
