It would be 7/8 because there is 7 filled in out of 8 ANDWER: 7/8
Answer:6
Step-by-step explanation:
*we solve every bracket alone
-(√2+1)² = [rule:1st *1st + 2*1st*2nd + 2nd*2nd]
2+2√2+1
3+2√2
-(√2-1)= [rule:1st*1st - 2*1st*2nd + 2nd+2nd]
2-2√2+1
3-2√2
-we write the whole equation
3+2√2+3-2√2 (+2√2 - 2√2) {positive and negative remove each other}
3+3=6
0 because you never included how many pages there were total
Let's call a child's ticket
and an adult's ticket
. From this, we can say:
,
since 116 tickets are sold in total.
Now, we are going to need to find another equation (the problem asks us to solve a systems of equations). This time, we are not going to base the equation on ticket quantity, but rather ticket price. We know that an adult's ticket is $17,000, and a child's ticket is thus
.
Given these values, we can say:
,
since each adult ticket
costs 17,000 and each child's ticket
costs 12,750, and these costs sum to 1,653,250.
Now, we have two equations:


Let's solve:


- Find
on its own, which will allow us to substitute it into the first equation

- Substitute in
for 

- Apply the Distributive Property


- Subtract 1972000 from both sides of the equation and multiply both sides by -1

We have now found that 75 child's tickets were sold. Thus,
,
41 adult tickets were sold as well.
In sum, 41 adult tickets were sold along with 75 child tickets.
