Solution: 2x + 5 = 28 Directions: Choose the algebraic equation for the word problem given below.

Q 1: If Mike's allowance was increased by $6, he would be earning twice what he is now. m + 6 = 2m 6m = m + m 6 + 2m = m

Q 2: Jill has 5 more pens than Kelly. j = k + 5 j = k - 5 k = j + 5

Q 3: Cathy got 10 fewer votes than Kim. Ron got three times as many votes as Cathy. The three students received a total of 90 votes. Write an equation in one variable that can be used to solve for the number of votes Kim received. (Hint: c = k - 10 r = 3c c + r + k = 90 ) c + 2r + 3k = 90 c + r + k = 90 k + (k-10) + 3(k-10) = 90

Q 4: Two more than three times a number is 20. 3x + 2 = 20 2x + 3 = 20 2x = 30

Q 5: Katie has twice as many tropes and Aron. a = k x 2 a x k = 2 k = a x 2

Q 6: 9 decreased by half a number is equal to 6. x - 9 = 6 9 - x/2 = 6 x/2 - 9 = 6

Q 7: Ben has 17 basketball trophies. b > 17 b = 17 b < 17

Q 8: The product of a number and 5 is equal to sum of that number and 14. 5x = x + 14 5x - 14 = x 5x = 14
