Step-by-step explanation:
First you must know that the sum of the interior angles of a triangle are 180. Once you know that, you just simply add 98+x=180 (you can use an variable as you see fit, doesn't need to be x). And then you simply solve for x by dividing 98 on both sides leaving you with 82.
Answer:
Whenever 
.
Step-by-step explanation:
We can play around with some numbers and develop some rules for this equation.
Note that the number 5 and -5 are used here, so let's try using 5 as a.
So 5 works. Let's try a random number like 3.
Okay, with this info we know that we might be able to develop one rule that 
. Just to test, let's try 0, -3, and -5.
Zero works.
-3 works.
-5 works. Now, this might stop here making the equation 
, so let's test a number outside of -5 - say -20.
Yes! This works, so a works for this equation as long as 
.
Hope this helped!

Answer:
$2.31 / lb
Step-by-step explanation:
If Vector bought 15.6 lbs of paintballs, and altogether the balls cost $35.99.
