Let's solve for x.
5x+15y=12
Step 1: Add -15y to both sides.
5x+15y+−15y=12+−15y
5x=−15y+12
Step 2: Divide both sides by 5.
5x
5
=
−15y+12

Answer:
x=−3y+12/5
Let's solve for y.
5x+15y=12
Step 1: Add -5x to both sides.
5x+15y+−5x=12+−5x
15y=−5x+12
Step 2: Divide both sides by 15.
15y

=
−5x+12

Answer:
![\text{D) }99^{\circ}](https://tex.z-dn.net/?f=%5Ctext%7BD%29%20%7D99%5E%7B%5Ccirc%7D)
Step-by-step explanation:
Define a cyclic quadrilateral by a quadrilateral that is circumscribed by a circle. In this case, since the quadrilateral shown is circumscribed by a circle, it is a cyclic quadrilateral.
A property of all cyclic quadrilaterals is that their opposite angles are supplementary, meaning they add up to 180 degrees. Since
and
are opposite angles in the quadrilateral, they must be supplementary. Therefore, we have the equation:
![\angle G+\angle I=180,\\81^{\circ}+\angle I=180,\\\angle I=180-81=\boxed{99^{\circ}}](https://tex.z-dn.net/?f=%5Cangle%20G%2B%5Cangle%20I%3D180%2C%5C%5C81%5E%7B%5Ccirc%7D%2B%5Cangle%20I%3D180%2C%5C%5C%5Cangle%20I%3D180-81%3D%5Cboxed%7B99%5E%7B%5Ccirc%7D%7D)
Answer:
x + 5 = 5
Step-by-step explanation:
Solution doesn't change as the x in the equation is 0 and the answer totals as 5 due to 5 plus 0 being 5
