Answer:
c (0,-4)
Step-by-step explanation:
-5x+y = -4
4x - 4y =16
Solve the first equation for y since we are using substitution.
-5x+y = -4
Add 5x to each side
-5x+5x+y = -4+5x
y = 5x-4
Substitute this equation y = 5x-4 into the second equation.
4x -4(5x-4) = 16
Distribute the -4
4x - 4(5x) -4(-4) = 16
4x-20x +16 = 16
Combine like terms
-16x +16 =16
Subtract 16 from each side
-16x+16-16 = 16-16
-16x =0
Divide by -16
x=0
But we still need to find y
y = 5x-4
y = 5(0) -4
y = -4
1 mile = 1760 yds
Therefore, if we multiply 1760 by 10 we will get 10 miles in yards
1760 * 10 = <em>17600 yards</em>
Hope it was helpful and clear.

Since Charles runs a 1/4 mile in 10 minutes, and 1/4 goes into 1 1/2 6 times, the answer is 10*6, which is 60.
Answer:
we can get 3/2 as the answer
