Answer:
The answer to your question is 9 adults and 2 children
Step-by-step explanation:
Data
adult ticket = $22
children ticket = $15
Total people= 11
total cost = $228
Number of adults = x = ?
Number of children = y = ?
Process
1.- Write equation to solve the problem
x + y = 11 Equation l
22x + 15y = 228 Equation ll
-Solve Equation l by x
x = 11 - y Equation lll
-Substitute equation lll in equation ll
22(11 - y) + 15y = 228
-Solve for y
242 - 22y + 15y = 228
-Simplify like terms
-7y = 228 - 242
-7y = -14
y = -14/-7
y = 2
-Find x
x = 11 - 2
x = 9
2.- Conclusion
There were 9 adults and 2 children.
Answer: <u>An atom is the basic unit of matter</u> and the defining structure of elements. The difference between an atom and a molecule is that <u>molecules are formed when two or more atoms bond together</u>. If molecules contain atoms of different elements, that substance is known as a compound. <u>Atoms make up molecules. </u>
This is a difference of perfect squares which is of the form:
(a^2-b^2)
And which always factors to:
(a-b)(a+b)
In this case:
(5x-8)(5x+8)
07:10 = 7:10 AM
17:30 = 5:30 PM
