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>

Answer:
c = 4y
Step-by-step explanation:
Are there more, Chihuahuas or Yorkies?
Does the word 'times' mean add, subtract, multiply or divide?
The way I look at it, there are more Chihuahuas and 'times' means multiply. Do you agree?
Therefore, I need to multiply 4 times the no. of Yorkies to get the no. of Chihuahuas
So, c = 4y
Now, I don't see an equation in the list to choose from. So, I don't know what to do from here. I am guessing that c = 4y is what you want.
C=100
r = 2
t = 4
P = 100*2^4 = 1600
The population of mice will be 1600 in four years.
-50/54 which reduces to -25/27. Hope this helps
-4 + 8 = 4;
4 - 16 = -12;
-12 + 32 = 20;
20 - 64 = -44;
-44 + 128 = 84;
84 - 256 = -172.
The sum of the first 7 terms in this series is -172.
I hope this helps!
