Answer:
45
Step-by-step explanation:

add 6 on both sides to eliminate it(doing this will get us closer to the variable)
x/3=15
multiply both sides by 3
x=45
hope this helps!
Answer:
178
Step-by-step explanation:
The first thing we need to do is take in all this information. We already know that the answer is between 0 and 7 because Line Segment AC is equal to 7. Second of all, it is recommended to solve this problem on paper to make it easier. You write the measurement under each individual Line Segment. Now we have to try to find a way how to subtract the Line Segments in order to get the measurement of Line Segment BC. If we were to write an equation. We would get mAB + mBC + mCD + mDE = mAE . We now try to think about the values that they give us to try to simplify it as much as possible. That's all that I can give you. I am sorry. This is a pretty tough and evil question.
