The range is the largest number subtracted by the smallest number.
28-4=24 is the range.
125/21 = 150/x
cross multiply
125x = 3150
x = 3150/125
x = 25.2 lbs....rounded up = 26 lbs <==
(3 x 2 = 6 - 2 x +4) + (-8x-3=-24) i think.
Slope = 2/1
Work is attached in the image provided.
First you subtract 4 to get it to the other side. Now the equation is -4=1/4x. Next, multiply both sides by 4 to isolate the x. Now you have -16=x.
