In any triangle, the sum of the measures of the angles is \(180^{\circ}\). In triangle \(A B C, \angle A\) is four times as large as \(\angle B\). Angle \(C\) measures \(20^{\circ}\) less than \(\angle B\). Find the measure of each angle.
Use the following information. A person has quarters, dimes, and nickels with a total value of 500 cents ( 5.00 dollar). The number of nickels is twice the number of quarters. The number of dimes is four less than the number of quarters. Write and solve an equation to find the number of each type of coin.
Simplify the expression. $$-4 x \div(-4)$$
You earn 9 dollar per hour. On major holidays, such as Thanksgiving, you earn twice as much per hour. You earned a total of \(\$ 405\) for the week including Thanksgiving.
