Choose the algebraic equation for the word problem given below.
: Katie has twice as many tropes and Aron.
k = a x 2
a = k x 2
a x k = 2
: 9 decreased by half a number is equal to 6.
x/2 - 9 = 6
9 - x/2 = 6
x - 9 = 6
: Jill has 4 fewer pencils than Matt.
j = m + 4
j = m - 4
m = j - 4
: Jill has 5 more pens than Kelly.
k = j + 5
j = k - 5
j = k + 5
: Ben has 17 basketball trophies.
b < 17
b > 17
b = 17
: Two more than three times a number is 20.
2x = 30
2x + 3 = 20
3x + 2 = 20
: Cod's money is twice as much as Peter's money.
c = p/2
c = 2p
p = 2c
: 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 )
k + (k-10) + 3(k-10) = 90
c + 2r + 3k = 90
c + r + k = 90
