Answer: Children tickets cost 7.50
Adult tickets cost 12.50
Step-by-step explanation:
Let a represent adult tickets
Let c represent child tickets
On the first day she sells 6 adult tickets and 5 children tickets for total of 112.50. This can be written as:
6a + 5c = 112.50 ...... equation i
On the second day she sells 8 adult tickets and 4 children tickets for the total 130. This can be written as:
8a + 4c = 130 ....... equation ii
6a + 5c = 112.50 ...... equation i
8a + 4c = 130 ....... equation ii
Multiply equation i by 4
Multiply equation ii by 5
24a + 20c = 450 ........ equation iii
40a + 20c = 650 ......... equation iv
Subtract iii from iv
16a = 200
a = 200/16
a = 12.50
Adult tickets cost 12.50
From equation ii,
8a + 4c = 130
8(12.50) + 4c = 130
100 + 4c = 130
4c = 130 - 100
4c = 30
c = 30/4
c = 7.50
Children tickets cost 7.50
Answer:
6 s^9 t^3
Step-by-step explanation:
When you multiply same variables with exponents, you want to add the expoenents.
6s^5t * s^4t^2
s^5 * s^4 = s^9
t * t^2 = t^3
6 * 1 = 6
6 s^9 t^3
Answer:
11.
Step-by-step explanation:
We are asked to evaluate the expression , when y=6 and z=3.
To evaluate our expression at given values we will just substitute y=6 and z=3 in our given expression.
According order of operations (PEMDAS) we will multiply or divide our expression from left to right.
Therefore, the value of our given expression at y=6 and z=3 is 11.
