105 degrees is the correct answer
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>

"Product of" tells you to use multiplication of the two terms
"square of x" = x²
"seven" = ... the number... 7
Your equation (your answer for these problems) can take a few forms:
x² · 7
7 · x²
7(x²)
(x²)(7)
7x²
So 9 Gallons a second is 2160 Quarts a minute
