Q 1: 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 2: Jill has 5 more pens than Kelly. k = j + 5 j = k - 5 j = k + 5

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

Q 4: Jill has 4 fewer pencils than Matt. j = m + 4 j = m - 4 m = j - 4

Q 5: If Mike's allowance was increased by $6, he would be earning twice what he is now. 6m = m + m 6 + 2m = m m + 6 = 2m

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: Cod's money is twice as much as Peter's money. c = 2p c = p/2 p = 2c

Q 8: Ben has 17 basketball trophies. b = 17 b < 17 b > 17
