Inequalities, Distributive Property, Order of Operations, Combining Like Terms

Place the following steps in the correct order of operations:

• Operations inside parentheses and grouping symbols

• Exponents and Roots

• Multiplication and Division L to R

• Addition and Subtraction L to R

Match the following terms to their meanings:

• Changing the grouping of terms (parentheses move)

• Associative Property

• Multiplying a term outside parentheses by everything inside

• Commutative Property

• Changing the order of terms (values move)

• Distributive Property

• You can add, subtract, multiply, or divide both sides of an equation by the same value

• Property of Equality

For each step in the equation with an empty box, click on the box, then click on the property that is used to accomplish that step.

Simplify the expression by distributing and combining like terms:

Solve the inequality shown here:

Nora set a goal to buy a new smart watch. She estimates the cost to be at least $350. She currently has $70 in savings. If she gets paid $40 per week to mow lawns, which inequality correctly represents the minimum number of weeks, w, that Nora has to mow in order to afford the smart watch?

• 70w + 40 ≥ 350

• 40w + 70 ≥ 350

• 70w + 40 ≤ 350

• 40w + 70 ≤ 350

Solve by combining like terms.

2x + 7y + 3 - y + 5x - 7

• 7x + 6y - 4

• 7x + 8y - 4

• 2x + 6y - 4

• 9x + 6y - 4

Solve by combining like terms.

7x + 4x

• 11x

• 11y

• 3x

• 28x
