Answer:
9 child tickets and 17 adult tickets were sold.
Step-by-step explanation:
Let the number of adult tickets sold be
and the number of child tickets be .
The theater sold a total number of 26 tickets.
This means that: .....eqn1
The theater made a total sale od $194.
This implies that:
...eqn2
We make the subject in equation 1: ...eqn3
Substitute equation (3) into equation (2)
Expand to get:
Put c=9 into equation (3) to get:
Therefore 9 child tickets and 17 adult tickets were sold.
Equation: <em />
diameter is twice the radius.
2.5^2=6.25
6.25 π ≈19.625
5 π ≈15.70
15.70*2=31.4
31.4+19.625=51.025cm^2
The example is 1 x (9 x 5) = 45
Using the associative property of multiplication, we basically rearrange the parenthesis to group the first two terms like so: (1 x 9) x 5
So this is why choice D (1 x 9) x 5 = 45 is the answer
This means that 1 x (9x 5) = (1 x 9) x 5 is a true equation
