Concepts

Which pair of terms are "like terms" and can be combined?

$(3/4)x$ and $(5/6)x$

$(3/4)x$ and $3/4$

$2x$ and $2x^2$

$0.5y$ and $0.5x$

What is $(2/3)x + (1/3)x$ ?

$x$

$(3/3)x^2$ , which simplifies to $x^2$

$(2/9)x$

$(1/3)x$

Procedures

Simplify: $(5/6)x - (1/3)x$ . Enter the coefficient of $x$ in the
simplified expression as a fraction (e.g., 1/2).

Simplify: $(3x + 2) - (x - 5)$ .

$2x + 7$

$2x - 3$

$4x - 3$

$2x + 3$

Expand $(1/4)(8x - 12 + 4y)$ . Enter the coefficient of $x$ in the
expanded expression.

What is the greatest common factor (GCF) used to factor $(2/3)x - (4/9)$
as $\text{GCF} \times (3x - 2)$ ?

$2/9$

$2/3$

$1/9$

$4/9$
