Lol right!
CPhill beat me at it haha but we're correct! ;)
x= 20
9x+14+56=250
9x+14=194
9x=180
x=20
Right on CPhill!! :D
I'm not pretty much understanding what you mean by this question? ¿Puedes explicar?
Seriously...
1. 60
2. Since the student chose a number let (x) be the number he chose:
2 * x - 138=102
2x=240
X=120 is the answer
Totally agree with CPhill :D
