Answer:

And if we solve for y we got:


And replacing we got:

And we got:

And for x we got:

So then the length would be 76 and the width we got 12.5
Step-by-step explanation:
For this case we have a rectangle. The perimeter is given by:

Where x represent the length and y the the width. We can set the following conditions:

And if we replace the conditions we got:

And if we solve for y we got:


And replacing we got:

And we got:

And for x we got:

So then the length would be 76 and the width we got 12.5
Answer:
Step-by-step explanation:
y = 0.80x + 2.50
a 7 mile ride......x = 7
y = 0.80(7) + 2.50
y = 5.60 + 2.50
y = 8.10 <=== the 7 mile ride cost $ 8.10
the ride cost 13.70.....y = 13.70
13.70 = 0.80x + 2.50
13.70 - 2.50 = 0.80x
11.2 = 0.80x
11.2 / 0.80 = x
14 = x <=== u travel 14 miles
1694/4 = 423,5
Answer: 423,5 hours.
