Well 32 minutes is half of an hour so 8 miles would be half of the full x miles
so 8 x 2 would be 16
16 miles per hour
Answer:
x = 6
Step-by-step explanation:
Substitute y = - 4 into the equation and solve for x
6x + 7(- 4) = 4x + 4(- 4) ← evaluate
6x - 28 = 4x - 16 ( subtract 4x from both sides )
2x - 28 = - 16 ( add 28 to both sides )
2x = 12 ( divide both sides by 2 )
x = 6
So 8x^2+8x+8-(-9x^2+2x+5) is going to be
8x^2+9x^2+8x-2x+8-5
Giving you
17x^2+6x+3
