What is the equation for Paulo's money problem if he spends $6 and has 1/4 of the original amount left?

• x + 6 = 1/4 * x

• x - 6 = 1/3 * x

• x - 6 = 1/4 * x

• x - 6 = 1/2 * x

• More than

How do you represent three consecutive integers in an equation?

• n, n + 3, n + 6

• n, n + 1, n + 2

• n, n + 2, n + 4

• n, n - 1, n - 2

What is the sum of three consecutive integers if their total is 93?

• n + n + 1 + n + 2 = 93

• n + n + 3 + n + 6 = 93

• n + n + 2 + n + 4 = 93

• n + n + 1 + n + 3 = 93
