Group consisting of several families visited an amusement park where the regular admission fees were ¥5,500 for each adult and ¥4,800 for each child. because there were at least 10 people in the group, each paid an admission fee that was 10% less that the regular admission fee. how many children were in the group? (1) the total of the admission fees paid for the adults in the group was ¥29,700(2) the total of the admission fees paid for the children in the group was ¥4,860 more than the total of the admission fees paid for the adults in the group.

Step-by-step explanation:

After the discount, each ticket was 90% of its original price, so ...

___

(1) The number of adults admitted was ...

  # adults = (total cost for adults)/(cost per adult)

  # adults = ¥29700/¥4950 = 6

__

(2) The amount paid for the children was ...

  child admission total = ¥29700 +4860 = ¥34560

The number of children admitted was ...

  # children = (total cost for children)/(cost per child)

  # children = ¥34560/¥4320 = 8

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
