Multiply the x values by -1/2, and then add three, that will give you the y values
I THINK,4=31
1=?
(1*31)/4=x
X=31/4
X=7.75minute to ride around the neighborhood once
It may not be correct
-3(2x-4)+8x-8
-6x+12+8x-8
2x+4
x=2
Set up a proportion
EA / EB = ED/ EC
16 / (5x + 2 + 16) = 12 / (12 + 24)
16/(5x + 18) = 12 / 36 Cross multiply
16 * 36 = (4x + 18)*12 Remove the brackets
576 = 48x + 216 Subtract 216 from both sides.
360 = 48x Divide by 48
360/48 = x
7.5 = x
