The sum of two consecutive odd integers is 244. What is the smaller integer?
119
125
123
121

Answer 1

2/5 (x - 4) = 2x
2/5x - 8/5 = 2x
-2x + 2/5x = 8/5
- 8/5x = 8/5
x = -1
answer
−1
--------------------
−ax + 4b > 9
-ax > 9 - 4b
x < (9-4b)/-a
x < (-4b +9)/-a

answer is
x < (-4b + 9) /-a
---------

$1128 - $72 = $1056

$1056 / $ 43 = 24.55

answer
Maximum 24 video games

24 (first choice)

-------------------------

The sum of two consecutive odd integers is 244. What is the smaller integer?

x + x + 2 = 244
2x + 2 = 244
2x = 242
x = 121

two consecutive odd integers are 121 and 123

answer
smaller integer is 121

121 (last choice)
