8 / 86 = 12 / x
cross multiply
(8)(x) = (86)(12)
8x = 1032
x = 1032/8
x = 129 pieces
Answer:
24x - 40
Step-by-step explanation:
8 x 3 = 24
8 x 5 = 40
24x - 40
So the ratios would look like this:
2.394 inches : 1 minute
x inches : 7.489 minutes
You need to do this: 7.489*1*2.394.
= 7.489*2.394
≈ 17.929 inches.
The rate of change is equal to the slope of a line. Given any 2 points on a line and you can calculate the slope (rate of change) of that line. The formula for rate of change is given by Δy/Δx which equals (y2-y1)/(x2-x1). Therefore, using the points given in the question and simply input them into our formula, we get ((4)-(3))/((-2)-(0)) = -1/2
