A delivery truck is transporting boxes of two sizes large and small. The combined weight of a large box and a small box is 80 pounds. The tuck is transporting 50 large boxes and 55 small boxes. If the truck is carrying a total of 4125 pounds in boxes, how much does each type of box weigh?

Large box:
Small box:

small=15 large=40

Step-by-step explanation:

x=large box

y=small box

55 = x + y

50x + 55y = 2825

50x + 55( 55 - x) = 2825

50x + 3025 - 55x = 2825

0 = 55x - 50 x + 2825 - 3025

0 = 5x - 200

200 = 5x

x=40

y = 15

eve and marks ratios are equivalent

step-by-step explanation:

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
