Answer:
4r + 4(r + 3) = 68
r = 7 miles per hour
r + 3 = 10 miles per hour
Step-by-step explanation:
distance = rate * time
a)
4r + 4(r + 3) = 68
Distribute
4r + 4r + 12 = 68
8r + 12 = 68
8r = 56
r = 7 miles per hour
r + 3 = 10 miles per hour
Answer:
Yes, I believe the answer is C because that is the only one that sounds reasonable.
If it were any of the other answers than it would either be intersecting or on the exact line and it is supposed to be perpendicular mean never touching.

Answer: 3 dollars per pound</h3>
Explanation:
The unit price is the price of 1 unit, in this case one pound. So we locate x = 1 on the x axis, draw a vertical line upward til we get to the diagonal line, and then draw a horizontal line until we reach the y axis. You should arrive at y = 3.
The sample space would be 27. The probability of getting 3 heads if you flip 3 pennies is 1/27.
Hope it helps! :)
