Answer:
The answer is 55.83
Step-by-step explanation:
It is 55.83 because the question is asking altogether so it is addition I added 48.24+7.59=55.83
Hope this helped
So these are our two equations: 
Before we can use elimination, subtract y on both sides of the first equation: 
Now we are able to use elimination. To eliminate the y variable, add the two equations together to get
. From here we can solve for x.
For this, just divide both sides by 3 and your first answer will be 
Now that we have the value of x, substitute it into either equation to solve for y:

<u>In short, x = 3 and y = 6.</u>
If two angles are supplementary, their measures add to 180 degrees.
Let’s name the angles A and B.
You can substitute or replace angle B in the first equation with the second equation like so:
4
So, angle A is 42.5 degrees and angle B is 137.5 degrees!
The question mark is 5. 8-5=3 and 12-5=7
