Today's tasks include preparing for the final exam, completing classwork and notebooks, and bringing a calculator to class tomorrow since phones cannot be used. The warm-up section of the notebook covers simplifying expressions, reviewing for the final exam, and solving a radical equation. The last warm-up question asks students to solve the equation 5x + 1 - 3x - 5 = 2 by squaring both sides, distributing, factoring, and solving for x to get the solutions of x = 3 or x = 7.

What was the price of each type of ticket?
3(6y + a = $17.50)
- 3y + 3a = $22.50
y = $2.00; a = $5.50

7. Sadly, we have reached the end, the last warm-up
question of the year..........

8. 5x  1  3x 5  2.
Set up the equation
so that there will be
only one radical on
each side of the equal sign.
Square both sides
of the equation.
Simplify.
Simplify by dividing
by a common factor of 2.
Square both sides of the
equation.
