Question

Help for 28 and must show work

Answer 1

weight to mass
weight:mass
weight/mass

take a randomweight and mass
lets say 20 mass and 196 weight
weight/mass=196/20=98/10

so

weight/mass=98/10
we need x
weight=1078

1078/x=98/10
times both sides by 10x
10780=98x
divide both sisdes by 98
110=x

ratio is 98/10 and x=110
B is the answer

Answer 2

Step 1: Find The Ratio (you can look at the numbers you are given to do this)

196/20 = 9.8
490/50 = 9.8
1274/130 = 9.8
1372/140=9.8

Your ratio is going to be 9.8 or 98/10


Step 2: Find x

1078/9.8 = 110

x=110
