Recall / Warm-Up

What is $\frac{3}{4} \times 8$ ?

$6$

$\frac{3}{32}$

$\frac{11}{4}$

$\frac{24}{4}$

Which two terms are like terms?

$5x$ and $5y$

$3x$ and $7x$

$4x$ and $4$

$x^2$ and $x$

Which expression is equivalent to $3(2x + 5)$ ?

$6x + 5$

$6x + 15$

$5x + 8$

$6x + 8$

Simplify: $\frac{1}{2}x + \frac{1}{4}x$

$\frac{3}{4}x$

$\frac{1}{8}x$

$\frac{1}{2}x^2$

$\frac{3}{6}x$

Simplify: $\frac{3}{4}x - \frac{1}{6}x$ . Express the coefficient as a fraction in simplest form.

Simplify: $(\frac{5}{6}x + 3) - (\frac{1}{3}x + 1)$ . Write the simplified expression.

Expand: $\frac{1}{3}(9x - 6)$ . Which is correct?

$3x - 6$

$3x - 2$

$3x + 2$
