The y-intercept is 10 hours and it represents the number of hours it took to empty one tank
Answer:
220 miles
Step-by-step explanation:
65 miles per hour for 2 hours — 65+ 65 = 130
60 miles per hour for 1.5 hours — 60 (for the 1 hour) + 30 (for the half hour) = 90
130 + 90 = 220
The correct answer to your question is 20x+25
Answer:
Multiply the first equation by 4.
Step-by-step explanation:
4(x+y=3) which gives
4x+4y=12
and
4x-y=7
Then subtract the two equations and the x variable will be eliminated.
