Answer:
See Below
Step-by-step explanation:
Take the the given information and compare to the question being asked
. So insert the x & y's of both equations (ima do y over x to make it easier)
divide 14/4
3.5 = 
then multiply both sides by 40 to isolate y
140 = y
Check by reinserting 140 and divide it by 40
Answer:
A. and D.
Step-by-step explanation:
To get the unit rate, you divide the y value by the x value.
180/15 = 12
The x value becomes a 1.
This means A. is correct.
Take the unit rate to find the profit for 20 scarves. To get 20, you multiply 1 by 20.
1 * 20 = 20
Do the same to 12.
12 * 20 = 240
This will give you the point (20, 240).
This means D. is correct.

Answer:
17/20
Step-by-step explanation:
3/4 + 4/5 - 7/10
1. Find the LCD (Least Common Denominator). The LCD is 20.
2. 20/4=5. 5*3=15. So, 3/4 becomes 15/20.
3. 20/5=4. 4*4=16. So, 4/5 becomes 16/20.
4. 20/10=2. 2*7=14. So, 7/10 becomes 14/20.
5. Your new equation is 15/20 + 16/20 - 14/20.
6. Solve from left to right.
7. 15/20 + 16/20= 31/20.
8. 31/20 - 14/20= 17/20.
