Solve. 1 nickel = 5 pennies; Multiply both sides by 7. Category 3 – 60 points

Solve: (6 + 5) = (11 X 1); Multiply both sides by 12 Category 3 – 80 points

Substitute and solve this equation where p = 4. (2 + 3) X p = (60 / 12); Divide both sides of the equation by 5. Category 3 – 100 points

Solve: 1. 7 X 9 = X 9 = Category 4 – 20 points

1. 12 X 12 = 2. 9 X 9 = Category 4 – 40 points

Is this equation balanced? 7 X 9 = (3 X 3) X (21 / 3) Category 4 – 60 points

Solve for p, so that the equation is balanced. 12 X 9 = (48 / 4) X (3 X p) Category 4 – 80 points
