Answer:
b. Sarah has driven "x" miles of a 35 mile trip.
Step-by-step explanation:
B makes the most sense because the reader does not know how many miles she has driven.
8 and 4 equals 32
3 and 4 equal 12.......
The answer to this expression would be 1.2x
Sense there's only a y, you'd assume y is 1 or 1y.
you'd make the 1 a negative 1 to get rid of the subtraction sign.
you'd add together the 2 ys making it 2y. then add -1 + 3, which would be 2.
so, the answer would be 2y + 2.
