What is a constant in algebra?

• A variable that can change value

• A fixed value that does not change.

• An equation that is always true

• A number that represents a range of values.

What is a variable in algebra?

• A variable is a symbol, often a letter, that represents an unknown value in an equation.

• A variable is a fixed number that does not change.

• A variable is a type of equation used to solve problems.

• A variable is a mathematical operation such as addition or subtraction.

Solve for m: 16 = m/8

• m = 64

• m = 128

• m = 32

• m = 256

Solve for u: 216 = u - 129

• u = 300

• u = 345

• u = 400

• u = 250
