A school band ordered hats for $3 and large T-shirts for $5. They bought 120 items in all for $520. Use a graph of a system of equations to find how many hats and T-shirts the band ordered.

Noel is hoping to make a profit (in $) on the school play and has determined the function describing the profit to be f(t) = 8t – 2654, where t is the number of tickets sold. what does the number 8 tell you?

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =

Solve the formula ax+ by = c for x.
