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

Aly knows that she doesn't want coffee, therefore she knows that not everyone wants coffee.
