State a hypothesis.....
Not always. Here's a statement that proves it wrong. 2 and 4 are a factor of 12. However, 8 is not a factor of twelve. In some cases though, it's right. 2 and 4 are a factor of 32. So is 8. So George is incorrect, it can only happen sometimes. Hope this helps.
Answer:
0.64
Step-by-step explanation:
1 and 1/2x+3/4x=5/8
combine x's
1 and 1/2x=4/4x+2/4x=6/4x
6/4x+3/4x=5/8=9/4x
9/4x=5/8
multiply both sides by 8
18x=5
x=5/18
x=5/18 or aprox 0.277777777777
