### Practice Test

Find the prime factorization of $756.$

Evaluate when $x=\mathrm{-2}$ and $y=3:$ $\frac{\left|3x-4y\right|}{6}$

Translate to an algebraic expression and simplify:

ⓐ eleven less than negative eight

ⓑ the difference of $\mathrm{-8}$ and $\mathrm{-3}$, increased by 5

Dushko has nickels and pennies in his pocket. The number of pennies is seven less than four times the number of nickels. Let $n$ represent the number of nickels. Write an expression for the number of pennies.

Convert

ⓐ $\frac{5}{11}$ to a decimal ⓑ $1.15$ to a percent

In the following exercises, simplify each expression.

$8+3\left[6-3\left(5-2\right)\right]-{4}^{2}$

$56\xf7\left(\mathrm{-8}\right)+\left(\mathrm{-27}\right)\xf7\left(\mathrm{-3}\right)$

$\mathrm{-5}+2{(\mathrm{-3})}^{2}-9$

$-\frac{7}{18}+\frac{5}{12}$

$\frac{9-3\xb79}{15-9}$

$\frac{5}{13}\xb747\xb7\frac{13}{5}$

$\mathrm{-4.8}+\left(\mathrm{-6.7}\right)$

$\mathrm{-12.04}\xb7\left(4.2\right)$

$\sqrt{\mathrm{-121}}$

$5x+\left(\mathrm{-8}y\right)-6x+3y$

$\mathrm{-3}\left(8x-5\right)$
