Skip to 7

1. Suppose you get a job selling T-shirts at a concert. You get $2 for each T-shirt you sell, but it costs you $5 to get into the concert. How many T-shirts will you have to sell in order to make $25?

2. Solve for   x   and check.   2(x - 1) + 4 = 3x - (2x - 3)

3. (2x2 - 3x + 5) + (x2 + 4x - 6)

4. (2x2 - 3x + 5) - (x2 + 4x - 6)

5. (2x2 - 3x + 5)(x2 + 4x - 6)

6. (2x2 - 3x + 5)/(x2 + 4x - 6)

In #6, use long division of polynomials.

7. Solve for   x   and check. 2x2 + x = 21

8. Divide
