Write an equation and solve.
5) Find three consecutive integers such that their sum is 99. Solve x + x + 1 + x + 2 = 99
algebraically. Let...
x = 1st integer
3x + 3 = 99
x + 1 = 2nd integer ­ 3 ­ 3
x + 2 = 3rd integer
3x = 96
3 3
The numbers are 32, 33 and 34.
x = 32
6) Find three consecutive even integers such that their sum is 42. Solve x + x + 2 + x + 4 = 42
algebraically. x = 1st integer
x + 2 = 2nd integer
x = 4 = 3rd integer The numbers are 12, 14 and 16.
3x + 6 = 42
­ 6 ­ 6
3x = 36
3 3
x = 12
7) April paid $3 per soda and a popcorn for $4.50. If April paid a total of $16.50, how many sodas did April purchase? 3x + 4.50 = 16.50
x = # of sodas
April bought 4 sodas
­ 4.50 ­4.50
3x = 12.00
3 3
x = 4
