Answer: z=83/c - 7 + t
Step-by-step explanation:
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10
<em>add 10 to each side</em>
<em>5x-10+10 = 10 + 10</em>
<em>5x=20</em>
5x = 0 <em>this is the error</em>
He needs to add 10 to each side
So the answer is (2c – 3) (2c – 3) or (2c – 3)^2
Answer: Blll's family has 70% of driving left.
Step-by-step explanation:
The total mileage of the trip = 3,000 miles.
miles driven so far = 900miles
