Answer:
70
Step-by-step explanation:
You have to find the vertical of x. To the right of the vertical, we see that there is an angle of 25 (since the 25 up top corresponds to that blank angle). Once you add 25 + 85 + x = 180 (since this is a straight line), we see that x is 70, and its vertical is also 70.
For this case we have the following equations:
revenue: y = 4x
cost: y = 1 / 2x + 280
We must match both equations:
4x = 1 / 2x + 280
From here, we clear the value of x:
4x-1 / 2x = 280
7 / 2x = 280
x = (2/7) * (280)
x = 80

jason needs to sell 80 posters so that the cost and revenue are equal
Think about what 9 is as a square root:

The answer which is closest to this is closest to 9.
Answer:
8 apples + 9 oranges = 43 y
Step-by-step explanation:
Cost of each apple
2y cents
Cost of each orange
3y cents
8 apples and 9 oranges
8*(2y) + 9*(3y) = 16y + 27y
= 43 y
