For exercises 1-8, use a number line graph to represent the inequality. $$ x<8 $$

For exercises 1-10, solve. $$ \frac{x}{6}=30 $$

For exercises 1-72, (a) solve. (b) check. $$ -x+9=14 $$

For exercises 1-72, (a) solve. (b) check. $$ 4=-5-x $$

For exercises 1-28, solve the equation for \(y\). Write the equation to match the pattern \(y=m x+b\). $$ -5 x=\frac{1}{6} y $$

For exercises 11-46, (a) solve. (b) check. $$ \frac{4}{7}=\frac{u}{84} $$

For exercises 37-52, (a) solve. (b) use a number line graph to represent the solution. (c) check the direction of the inequality sign. $$ 7 x+3<52 $$

Solve \(A=L W\) for \(L\)

For exercises 37-52, (a) solve. (b) use a number line graph to represent the solution. (c) check the direction of the inequality sign. $$ 4(2 x-6) \leq 5(x-9) $$

The multiplication and division properties of equality do not allow both sides of an equation to be multiplied or divided by 0 . Explain why you think zero cannot be used.
