Make two equations
C = children, A = adults
2.50C + 7.00A = 7950
(C + A = 2100) * 2.5
2.50C + 2.50A = 5250
Use elimination
4.5A = 2700, A = 600
2100 - 600 = 1500
Solution: 600 adults, 1500 children
For this case we have that by definition of properties of powers and roots, it is fulfilled that:
\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}
n

=a

So:
\sqrt [4] {9 ^ {\frac {1} {2} x}} = 9 ^ {\frac {\frac {1} {2}} {4} x} = 9 ^ {\frac {1} {8} x}

So, we have to:

Option B

Answer:
x=7.5
Step-by-step explanation:
To show that the triangles are similar, we simply need to show that all sides are proportionate.
So, we create a proportion
Then we plug in the values
and 
can be simplified to 
, so that is our ratio of similarity
then we know
Now solve
1. Cross multiply
2×(2x-5) = 22
2. Distribute
4x-8 = 22
4x=30
x=7.5
There is your answer, x=7.5
Hope this helped.
Its (2+h)+3 that's the answer
