How do I find x in this problem?
Answers
Answer:
125
Step-by-step explanation:
Since its a hexagon the interior angles equal to 720 degrees.
Because (n-2)180 equals the number of sides. So, (6-2)180 = 720.
Now for x,
120 + 130 + 100 + x + 135 + 110 = 720
595 + x = 720
x = 125

Answers
Answer:
Step-by-step explanation:
Since this is a test/homework, I'll give you a hint.
For a linear graph, if you took a ruler, and traced the "dots", it should always be in a straight line.
Another way, is finding a pattern. I can't really explain this so much, since it's fairly basic. Just find two dots, and see if they are similar in any way. If they are, good job! Find another. If their isn't, maybe try searching for another.
The third way: You could use the equation mx+b=y, but this is just a bit ridiculous for this problem, since you could just eye it.

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that the number of days required to build is inversely proportional to with the number of workers.
One house was built in 147 days by 4 workers.
So,
147 x 4 = 588
Now the days to build a similar house with 42 workers
588/ 42 = 14
