1. The sum of a number n and 4 is 12. Solve and check the equation. 4•n = 12 n + 4 = 12 12 - n = 4 12 ÷ n = 4 n = 2. The product of a number x and 5 is 20. Solve and check the equation. 5•x = 20 x + 5 = 20 x - 5 + 20 20 ÷ x = 5 x = 3. The quotient of a number y and 2 is 8. Solve and check the equation. 2•y = 8 y + 2 = 8 y ÷ 2 = 8 8 - y = 2 y = 4. 6 is 1 less than a number m. Solve and check the equation. 6 ÷ m = 1 m - 1 = 6 6 - m = 1 1•m = 6 m = 5. A number n decreased by 7 is 11. Solve and check the equation. n = 7•n = 11 n + 7 = 11 11 ÷ 7 = n n - 7 = 11 6. The quotient of a number x and 3 is 60. Solve and check the equation. x ÷ 3 = 60 3•x = 60 x - 3 = 60 3 + x = 60 x = 7. The area of a 9 foot long floor rug is 36 square feet. Write and solve an equation to find the width of the rug. l = 9 ft. A = 36 ft.2 w = ? width = ft. ft. |
