Open book open note quiz.
Complete on a separate sheet of paper, then staple to
assignment and turn into tray when finished.
1. 1/3 x – 7 = 32
2. 2y + 1/5 = 3/10
3. 2/3x + (-3) = 11
4. ½ c – 2/3 = 1/6
5. x – (-2/4) = 1/3

When exercising, a person’s pulse rate
should not exceed a certain limit, which
depends on his or her age. This
maximum rate is represented by the
expression 0.8(220 – a), where a is age
in years. Find the age of a person
whose maximum pulse is 152.
Bell Work
1) Solve. Two thirds of a
number plus seven is negative
three.
Solve each equation.
2) (34 – x) ÷ 9 = 2
Write an equation to solve
Each 4 & 5.
3) Find three consecutive integers
whose sum is zero
4) Joel purchased a pen for
$1.29 and six notebooks at
the school store. If the total
bill was $12.63, what was
the cost of one notebook?

The student will be able to solve
equations with variables on each
side of the equals sign.

8 + 5s = 7s – 2

1/3(18 + 12q) = 6(2q – 7)

8(5c – 2) = 10(32 + 4c)

4(t + 20) = 1/5 (20t + 400)
