Answer:
3 adult tickets and 4 child tickets
Step-by-step explanation:
a + k = 7
a = 7 - k
12a + 9k = 72
12a + 9k = 72
12(7 - k) + 9k = 72
84 - 3k = 72
84 - 3k = 72
3k = 12
k = 4
a = 3
The number of adult tickets purchased is 3 and the number of child tickets purchased is 4.
Given that, adult tickets cost $12 and child tickets cost $9.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
If they spent $72 total and purchased 7 tickets.
Let the number of adult tickets be x, then the number of children tickets will be 7-x.
Now, 12x+9(7-x)=72
⇒ 12x+63-9x=72
⇒ 3x=72-63
⇒ 3x=9
⇒ x=3
So, 7-x=4
Therefore, the number of adult tickets purchased is 3 and the number of child tickets purchased is 4.

Answer:
[tex] m\angle 1 = 115\degree \\\\
m\angle 2= 130\degree \\\\
m\angle 6= 60\degree \\\\[/tex]
Step-by-step explanation:
[tex] m\angle 1 = m \angle 5\\(corresponding \: \angle s) \\\\
\because m\angle 5 = 115\degree \\
\therefore m\angle 1 = 115\degree \\\\
m\angle 2 = m \angle 7\\(exterior \: alternate \: \angle s) \\\\
\because m\angle 7 = 130\degree \\
\therefore m\angle 2= 130\degree \\\\
m\angle 4 + m\angle 5= 180\degree\\\\
6y\degree + (13y - 10)\degree = 180\degree\\\\
(19y - 10)\degree = 180\degree\\\\
19y - 10 = 180\\\\
19y = 180+ 10\\\\
19y = 190\\\\
y = \frac{190}{19}\\\\
y = 10\\\\
m \angle 4 = 6y\degree \\\\
m \angle 4 = 6\times 10\degree \\\\
m \angle 4 = 60\degree \\\\
\because m\angle 6 = m \angle 4\\( alternate \: \angle s) \\\\
\therefore m\angle 6= 60\degree \\\\[/tex]
A balloon artist wants to make 6 different ut the kinds of balloon animals. She needs 4 balloons to make each animal. If the balloons come in packs of 8, how many packs will she need to buy? Part A Explain what you need to find first to solve the problem.
Answer:
She will need to buy 3 packs to make 6 different balloon animals.
Step-by-step explanation:
Given that the balloon artist wants to make 6 different animals, and each animal involves using 4 balloons, to make those 6 animals she must use 24 balloons, as the following calculation shows:
6 x 4 = 24
Now, since the balloons come in packs of 8 units, to make those 6 animals she must buy 3 packs of balloons, as this calculation also shows:
24 / 8 = 3.
