Answer:
Each sweater costs $35.
Step-by-step explanation:
First subtract the total price ($160) by the price of the shirt ($20).
160 - 20 = 140
Now were left with $140. Since Katie bought 4 sweaters, divide 140 by 4.
140/4 = 35
This means that each sweater was $35. If you want to make sure this is correct just multiply 35 by 4 and then add the $20. You should end up with $160.
35 x 4 = 140
140 + 20 = 160
Question:
A new auditorium is being built for a college. The balcony has 200 seats. The floor has 25 rows with x seats in each row. The number of people in the auditorium must be under 750 to meet safety regulations. What is the solution of this inequality, and what is its meaning?
Answer:

Number of seats in a row must be less than 22
Step-by-step explanation:
Given
Total = Less than 750
Current Seats = 200
Rows = 25
Seat per row = x
Required
Represent as an inequality
The scenario will be represented as:

Substitute 200 for Current Seats

Substitute 25 for Rows


Substitute <750 for Total.
The equation then becomes

Solving further:




This means that:
Number of seats in a row must be less than 22

Step-by-step explanation:
- Euler path - uses every edge of a graph exactly once
- Euler circuit - uses every edge of a graph exactly once
- Euler path - starts and ends at different vertices
- Euler circuit - starts and ends at the same vertex
Answer:x=2
Step-by-step explanation:
3(x-2)=6x-12
3x-6=6x-12
Collect like terms
6x-3x=12-6
3x=6
Divide both sides by 3
3x/3=6/3
x=2
