X=number of student tickes
y=number of adult tickets
total cost=8x+10y=1198
x+y=130
multipy second eatuion by -10 and add to first
-10x-10y=-1300
<u>8x+10y=1198 +
</u>-2x+0y=-102<u>
</u>
-2x=-102
divide both sides by -2
x=51<u>
</u>
51 student tickets sold<u>
</u>

Step-by-step explanation:
Answer:
B. (6,-2)
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2
The center of the circle is (h,k)
So, in this problem, h is 6 and k is -2, so the center of this circle is (6,-2).
95°.
Since the angle inside of a triangle equal 180° we need to find the angles inside of the triangle. The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°.
Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.
Hope this helps :)
