Answer:
3.25 and -2.651639344262295...
Step-by-step explanation:
if 0.5(r + 2.75) = 3, then r = 3.25
if 30.5(r + 2.75) = 3, then r = -2.651639344262295...

Answer:
A) 1,492
B) 1,908
Step-by-step explanation:
A) The equation set up for this part is 1,542-50=1,492 We know that we're subtracting 50 from 1,542 because it say that the plane starts below sea level.
B) The equation set up for this part is 3,400-1,492=1,908 We know that we're subtracting the answer from part A from 3,400 because the plane will need to climb the difference in order to reach 3,400.
