and a to represent adult tickets.
b. 125 more child tickets than adult tickets were sold. That can be modeled using the equatic
c = 125 + a. How many child tickets were sold? How many adult tickets were sold? Show
your work.
Answers
Answer:
a. 12a + 8c = 5500
b. 225 adult tickets
350 child tickets
Step-by-step explanation:
a. 12a + 8c = 5500
b. 12a + 8(125 + a) = 5500
12a + 1000 + 8a = 5500
20a = 4500
a = 225 adult tickets
125 + a = 125 + 225 = 350 child tickets

Answers
Answer:
$123.20
Step-by-step explanation:
First, convert 12% into a decimal, 12% = .12, now we multiply the discount by the original, so .12x140 which equals $16.80 then we subtract 16.8 from 140 giving you $123.20.

The coordinates of the vertices of a triangle are A( 2,3) , B ( 9,1) , C ( 12,14) Suppose each coordinate is multiplied by 3. What is the perimeter of this triangle?
Answers
9514 1404 393
Answer:
about 106.5 units
Step-by-step explanation:
The length of each side is found using the distance formula:
d = √((x2-x1)^2 +(y2-y1)^2)
For example, the length of side AB is ...
d = √((9 -2)^2 +(1 -3)^2) = √(7^2 +(-2)^2) = √53 ≈ 7.28
The other side lengths are calculated the same way. The sum of side lengths of the given triangle is ...
AB +BC +CA = 7.28 +13.34 +14.87 = 35.49
__
Multiplying each coordinate by 3 effectively dilates the triangle by a factor of 3 about the origin. That increases the perimeter by a factor of 3, so it is ...
3(35.49) ≈ 106.5 . . . . units
