Let x = the total cost of gas, dollars.
Originally, each of the three friends was to pay x/3 dollars each.
Finally, with two more friends added, the cost became x/5 dollars each.
The savings for each of the original three friends is $11, therefore
x/3 - x/5 = 11
(2x)/15 = 11
x = (11*15)/2 = $82.50
Answer: The total cost of gas is $82.50
Answer:
(2x,2y) .
Step-by-step explanation:
coordinate increases by times 2.
67.38 degrees
To find this, follow the steps below:
cos (B) = 5/13
cos -1 (cos(B)) = cos-1 (5/13)
The cos-1 and cos cancel each other out.
B = cos-1 (5/13)
B = 67.38
