Answer:
2 29/36
Step-by-step explanation:
So circle the two signs., so the problem is now this:
1/4+4/3+1 2/9
Then you find the GCM, or Greatest Common Denominator.
It is 36. Then, you re-write the new answers
9/36+ 48/36+ 1 18/36
Now we have this:
1 65/36
The answer is 2 29/36
Answer:
112
Step-by-step explanation:
So, we know that a triangle's sides must add up to have a sum of 180. If you add up your given lengths and you should get 47, not including x. Then if you look at the left side/the one without a given length and it should be identical to the 21, so you know that side is 21. So now add 21 to 47, you should get 68. Finally, you subtract 68 from 180 like this: 180-68, and it should equal 112. So you're answer is 112.
