Answer:
Step-by-step explanation:
The starting equation is
12-(3x+13)=0
First add 3x+13 to both sides so that only 12 is on the left
12=3x+13
now subtract 13 from both sides to isolate your variable
-1=3x
Finally divide both sides by 3 to get your final answer
x=-1/3
Answer:
2, 1/3 inches in 3/4
basically you multiply the denominator to match the other problem so 1/3 becomes 4/12 and 3/4 becomes 9/12
so there are 2 1/3 inches in 3/4, this is a sort of rough explanation I reccomend going on Khan Academy and looking for something to help you there
Answer:
67 people were still left waiting in line.
Step-by-step explanation:
If there are 65 plus 11 more, there'd be 76 people in line.
I guess the fact that it says "waiting in two lines" can be completely discarded because bottom line is 9 people got their drinks- which means that "waiting in two lines" means nothing.
76 - 9 = 67 people still left waiting in line.
