Answer:
n+3
Step-by-step explanation:
5/7
6*5/6*7
30/42
30/42 = 30/42
Yes, 5/7 and 30/42 form a proportion.
Take 2000 divide 76 =26.3 so the elevator can carry 26 boxes
(22 x sin(65))/sin(53) =24.96604654 rounded of to nearest tenth = 25
So X = 25
Put them into y=mx+b
y=1/3x -1
y=2/3x-4
Graph them. Where they touch is your answer. No touch? No solution. Same line? Infinite solutions.
Second set: Same thing.
Solution to first set is (9,2)
