Answer:
- x = 37 1/2
- x = 2
Step-by-step explanation:
Parallel lines divide transversals proportionally. I like to write the proportions so the variable is in the numerator. Then the solution is obtained by multiplying by the denominator of the variable term.
1. x/20 = (46 -16)/16
x = 20(30/16)
x = 37.5

2. (x +4)/13.5 = 4/9
x +4 = 13.5(4/9) = 6
x = 6 -4
x = 2
Answer:r<4/7
Step-by-step explanation:
35r-21<-35r+19
Collect like terms
35r+35r<21+19
70r<40
divide both sides by 70
70r/70<40/70
r<40/70
r<4/7
