Get started for freeDISTRIBUTIVE PROPERTY Use the distributive property to rewrite the expression without parentheses. $$ -2 t(12-t) $$
SIMPLIFYING EXPRESSIONS Simplify the expression by combining like terms. $$ 4+a+a $$
LEAVING A TIP In Exercises \(83-85\), use the following information. You and a friend decide to leave a \(15 \%\) tip for restaurant service. You compute the tip, \(T,\) as \(T=0.15 C,\) where \(C\) represents the cost of the meal. Your friend claims that an easier way to mentally compute the tip is to calculate \(10 \%\) of the cost of the meal plus one half of \(10 \%\) of the cost of the meal. Write an equation that represents your friend's method of computing the tip.
EVALUATING EXPRESSIONS Evaluate the expression. $$ 6-(-8)-11 $$
LOGICAL REASONING Decide whether the statement is true or false If false, rewrite the right-hand side of the equation so the statement is true. $$ \frac{2}{9}\left(\frac{1}{3}-\frac{4}{9}\right) \stackrel{?}{=} \frac{2}{9}\left(\frac{1}{3}\right)-\frac{2}{9}\left(\frac{4}{9}\right) $$
