Answer:
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
Step-by-step explanation:
Let w represent weight here. Then 0.05w = 300 lb.
300 lb
Solving for w, w = ------------- = 6000 lb (3 tons)
0.05
plug a=2 and b=4 in the expression
5(2)+7(4)
simplify
10+28
solve
=38
4/3(6/1) should give you 12
11x = -7y
this is the answer because you combine the x together
