Create equations:
10X+15y=2575.
X+Y=210.
Solve for X: X=210-Y, and sub it into the other equation: 10(210-Y)+15Y=2575. Solve for Y: 2,100-10y+15y=2575, 5y=475, y=95.
Sub Y into the original problem: X+95=210. Solve: X=115.
The first mechanic charges $115 per hour and the second charges $95 :)
Answer:
The perimeter is 100 ft
Step-by-step explanation:
Width = 9 ft
It is five times as long as it is wide
Length = 5*width = 5*9 = 45 ft
P = 2(l+w)
=2(45+5)
=2(50)
= 100 ft
O 5(-8) = -40 this is the correct one and the question ask except
