A group of people pays$720 for admission tickets to an amusement part. The price of an adult ticket is $15 and a child ticket is $8. There are 25 more adults than children. How many children are in the group?

15

Step-by-step explanation:

Set the number of children to n.

The number of adults is, thus, n + 25.

The total price of admission is $720, made up of adult tickets and child tickets.

The children paid $8 per child, or

8 * n

The adults paid $15 per adult, or

15 * (n + 25)

These sum of these is equal to the total cost of $720.

8*n + 15*(n + 25) = 720

8n + 15(n + 25) = 720

Multiplying 15 with both n and 25.

8n + 15n + 25*15 = 720

8n + 15n + 375 = 720

Subtracting 375 from both sides.

8n + 15n + 375 - 375 = 720 - 375

8n + 15n = 345

Adding together 8n and 15n.

23n = 345

Dividing both sides by 23.

n = 345/23 = 15

n = 15

As n is the number of children, there are 15 children in the group.

15

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
