Answer:
see explanation
Step-by-step explanation:
Inequalities of the type | x | ≤ a always have solutions of the form
- a ≤ x ≤ a
Given
| x - 1 | ≤ 1 then
- 1 ≤ x - 1 ≤ 1 ( add 1 to each of the 3 intervals )
0 ≤ x ≤ 2
Since we require an integer solution then x = 0, 1, 2
Answer:
c
Step-by-step explanation:
f
Please provide a picture of the number line you have in front of you, otherwise, we can't help you very much until we see what you're seeing.
The dashed boundary line means that the solutions are not on the boundary line. It is used for < and >
A=adult ticket c= children ticket
12c+3a= 162
8c+3a=122
Multiply the second by -1.Add both
And you have
4c=40
Divide both sides by 4
c=10..
The price for 12 children is $120
The price for 3 adults is $162-120= $42
Each adult pays $12
Each child pays $10
