Stanley's unit rate is 30 miles per gallon ( represented by:

)
Carla's unit rate is 36 miles per gallon ( represented by:

)
Carla's unit rate is higher than Stanley's. (mention the slope being steeper on the graph, because I have the same vacation homework.)
Answer:
x = 11
Step-by-step explanation:
well you take the base equation 11*x + 1*x = 286
( x being hours and y being the number of miles)
then you put in the numbers of the question it gives you 11x + 15x = 286 then you should add 11x and 15x together because they have the same variable which gives you 26x = 286 then you divide 286/26 so that you get x = 11
8*40 = 320 * 2 = $640 for the 2 workers
640/2000 = 0.32
labor cost is 32% of the revenue
ANSWER
The midpoint of both diagonals is

EXPLANATION
We can use either diagonals to determine the midpoint.
We use the midpoint formula

Let us use the first diagonals H(-2,2) and J(4,-2)



Using the second diagonals also gives,
