I’m not sure but can 10 nickels work?
Answer:
Second side = x feet
First side = x - 2 feet
Third side = x - 4 feet
Perimeter is 15 feet
15 = x + x - 2 + x - 4
Solve for x and then plug your x-value back into the three sides given above
Answer:
(1, -5)
Step-by-step explanation:
Solve the system by setting the equations equal to each other, and solving for x:
-7x + 2 = 9x - 14
2 = 16x - 14
16 = 16x
1 = x
So, the x coordinate of the solution will be 1.
Plug in 1 as x into one of the equations, and solve for y
y = -7x + 2
y = -7(1) + 2
y = -7 + 2
y = -5
So, the y coordinate is -5.
The ordered pair solution is (1, -5)
