4Examples Translate each sentence into an equation. The sum of six and a number t is twelve.The difference between a number f and three is fifteen.Five increased by the product of a number y and seven is nineteen.The quotient of a number w and five decreased by four is zero.
5Examples The product of six and a number g is the same as thirty-two. Four times the sum of a number h and six is equal to fifty.Seven plus the product of a number x and five is as much as ten.The square of a number y plus two equals twenty-four.
6Translate this sentence into an equation Translate this sentence into an equation. A number c multiplied by six is equal to two more than d.A. 6c = d + 2B. 2c = d + 6C. c = d + 2D. c = 6(d + 2)
7Translate this sentence into an equation Translate this sentence into an equation. Three less than a number a divided by four is seven more than 3 times b.A.B.C.D.
8Translate the sentence into a formula Translate the sentence into a formula. The area of a circle equals the product of and the square of the radius r.A. A = + r2B. A = r2C. A = 2rD. A = 2r +
9Examples Translate each equation into a sentence. 6z – 15 = 45 y2 + 3x = w25u2 + 2 = 15
10Translate the equation into a verbal sentence. A. Twelve minus four divided by b is negative one.B. Twelve less than four divided by b equals negative one.C. Four minus twelve divided by b equals negative one.D. Twelve divided by b minus four equals negative one.
11Translate the equation into a verbal sentence. 5a = b2 + 1 A. Five plus a equals b squared plus one.B. Five times a equals twice b plus one.C. Five times a equals b squared plus one.D. The quotient of five and a equals b squared plus one.
