Ill take the 52.20 aint no splitting
Start from the last plane.
Rachel's plane flew 20 ft.
Darren's plane flew twice as far as Rachel's,
so Darren's plane flew 2 * 20 ft = 40 ft.
Amanda's plane flew 19 ft farther than Darren's,
so Amanda's plane flew 40 ft + 19 ft = 59 ft.
Answer:
3x - 1
Step-by-step explanation:
Note that you are adding the parenthesis together. In this case, you can disregard the parenthesis. Combine like terms (terms with the same amount of variables):
2x + 1x - 3 + 2
(2x + 1x) + (-3 + 2)
3x + (-1)
3x - 1
3x - 1 is your answer.
