Answer:
83.5
Step-by-step explanation:

18+11v=w-13t
18+11-w=-13t
13t=w-11v-18
t=1/13w - 11/13v - 1 5/13
Hope this helps :)
So 9x<18 can be factored out into
9(x)<9(2)
you can divide both sides by 9
x<2
so the solution is any number more than 2, but not 2
The answer should be 101.
Answer:
= x(a+b)(a-b) . x(b+c)(b-c) .x(c+a)(c-a)
