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
Answer:
The perimeter is 22.
Step-by-step explanation:
The perimeter formula (it sometimes varies) is 2(b+h)
b being base (in this example, 6)
h being height (in this example, 5)
So now, with substitution, we are left with:
2(6+5)
Which simplifies down to:
2(11)
22

Rewriting the term we get: 
Step-by-step explanation:
We need to find the common factor of the expression: 
A common factor is the term that is common in all the terms of the expression.
In the given expression the common factor is: 4X because it is common in both terms
So, Common factor is 4X
Rewriting the term we get:
