60 miles per hour
distance=rate times time
first part
rate=60mph
time=3h
distance=60mph times 3h=180 miles

part 2
time=2 hours
rate=70mph
distance=70mph times 2h=140miles

total is 180mi+140mi=320miles

Which equation represents a line which is parallel to the line 7y - 4x = -14?
iVinArrow [24]
Answer: Any line with a slope of 4/7 and a y-intercept that is NOT -2

You should first turn the equation into y intercept form:
7y - 4x = -14; Add 4x from both sides
7y = 4x - 14; divide 7 from both sides
y = 4/7x - 2

Since you did not include choices, the answer will be the line with the slope 4/7 and without the y-intercept -2, because lines that are parallel will always have the same slope.

Example Answers: y = 4/7x + 2, y= 4/7x - 4
y = 4/7x + 10

30

Step-by-step explanation:

If they are parallel then the 2 labelled angles sum to 180.

2x+50+5x-80=180

7x-30=180

7x=210
