Answer:
Adult tickets = 18
Children tickets = 25
Step-by-step explanation:
We can write 2 equations and solve:
let number of adult tickets be a and number of children tickets be c
Adult ticket cost is 8 and children cost is 5 and total money is 269, thus:
1. 8a + 5c = 269
Also, he sells seven more children's tickets than adult tickets, thus:
2. c - 7 = a
Now substituting 2 into 1, we can solve for c:
8a + 5c = 269
8(c-7) + 5c = 269
8c - 56 + 5c = 269
13c = 325
c = 325/13 = 25
Now using equation 2, we can solve for a:
c - 7 = a
25 - 7 = a
a = 18
So, 18 adult tickets and 25 children's ticket
Answer:
The formula to calculate the total surface area of a cylinder is expressed as, total surface area of cylinder = 2πr(r + h). This total surface area includes the area of the 2 bases (2πr2) and the curved surface area (2πrh). Here 'r' is the radius and 'h' is the height of the cylinder.

Answer:
x = 7
Step-by-step explanation:
You solve a linear equation by putting the variable on one side of the equal sign and a constant on the other side. Here, variables and constants are on both sides of the equal sign, so you need to separate them.
The basic idea is that you add the opposite of any term you don't want. Whenever you perform any operation (like "add"), <em>you must do it to both sides of the equation</em>.
We observe that x-terms have coefficients of 10 and 9. We choose to add the opposite of 9x to both sides:
10 -9x -5 = 9x -9x +2
x -5 = 2 . . . . simplify
Now, we still have -5 on the left, where we don't want it. So, we add its opposite (+5) to both sides:
x -5 +5 = 2 +5
x = 7 . . . . simplify
The solution is x = 7.

<em>Additional comment</em>
If we were to end up with an x-coefficient other than 1, we would divide both sides of the equation by that coefficient. This will leave the x-term with a coefficient of 1.
