Answer:
It should be 5x-6y=30
Step-by-step explanation:
The values have being matched to the variables that they represent here:
- x-variable: the number of hours Sam works at the airport
- y variable: the amount in dollars that Sam has after paying back Daniel
- 12: amount in dollars that Sam earns per hour.
- 40: the amount in dollars Sam owes Daniel
<h3>How to solve for the equation.</h3>
The equation of this form y = 12x-40
The variable y has been said to be the amount sam has after Daniel has been paid.
X is the amount that has to be multiplied by what he earns in dollars by the hour.
40 dollars is the amount that he owes which is going to be subtracted from what he earns by the hour.

10 inches would make him taller than 70, 9 inches would make him exactly 70
Answer:
8i + 4
Step-by-step explanation:
Add/subtract like terms:
7 - 3
= 4
-4i - (-12i)
-4i + 12i
= 8i
Add these together:
8i + 4
So, the simplified expression is 8i + 4
Answer:
7
Explanation:
From the question, we're told that triangles AMY and MEG are similar. If triangle AMY has sides AM = 5, MY = 7, and AY = 3 then we can find the side lengths of triangle MEG since we're told from the question that it is a dilation of AMY by a scale factor of 1/3.
So all we need to is multiply the corresponding sides of AMY by 1/3, so we'll have;
We can then go ahead and find the perimeter of MEG. Note that to find the perimeter of a triangle, we add all the length of its sides;
The perimeter of MEG is 7.
