Answer:
x = 10.75
Step-by-step explanation:
To find the value of x, we need to know the equation for the perimeter of a rectangle. This equation is:
P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
We are given P = 84, L = 3x -1 , and W = x. Now we just plug these values in and solve for x.
P = 2L + 2W
84 = 2 ( 3x - 1 ) + 2 ( x )
84 = 6x - 2 + 2x
84 = 8x - 2
86 = 8x
86 / 8 = x
43 / 4 = x
(40 + 3) / 4 = x
10.75 = x
Hence, the value of x = 10.75.
Cheers.
Answer:
<h2>
B. 7.71 hours</h2>
Step-by-step explanation:
If he rode 27 miles in 2 hours then that means he rode 13.5 miles in 1 hour because 13.5 is half of 27. This also means that he was moving at 13.5 mph. He reduced his speed on the return trip by 10 mph so, 13.5 - 10 = 3.5. Now that we know he was going 3.5 mph on the return, we can multiply 3.5 by 7.71 to get 27 since that's how far the ride was. 3.5 x 7.71 = 26.985. It's not exactly 27 but it's a lot closer than the rest.
