15 = 7+2x or 15= 2x + 7 is the equation and x=4
Answer:
The solution to the system of equations be:
Step-by-step explanation:
Given the system of equations
Let us solve the system by the elimination method
Arrange equation variables for elimination
subtracting the equations
so the system of equations becomes
solve 5x for x
Divide both sides by 5
Add 6 to both sides
Therefore, the solution to the system of equations be:
Answer:
16.75 meters
Step-by-step explanation:
This problem is a plug in problem.
H = 0.20x + 12.75
we plug in 20 for x which gives us
(0.20 * 20) + 12.75
which equals
4 + 12.75
giving us
16.75 meters
