Answer:
Step-by-step explanation:
So if the delivery person weights 160 lbs than we’re going to subtract 670-160=510 next we divide 40 into 510 which is 12.75. Which means that he can bring 12 boxes.
Answer:
12
Step-by-step explanation:
max cap 670lb- delivery person 160lb weight left 510lb
weight 510lb/each box 40lb number of boxes 12.75lb
each box 40lb times number of boxes 12lb 480lb+160lb 640lb
so your still have 30 lb before max weight of elevator

Answer:
110
Step-by-step explanation:
longest side would by 40 so 40 - 20 = 20. Add all the sides up 25+25+40+20=110
First you'd substitute x= y-3 in the first equation. 10(y-3) -10y= 1 10y - 30 -10y= 1 The y's cancel each other out, so you're left with -30= 1. That means there's no solution :)
