Answer:
or 3
Step-by-step explanation:
To find the slope find two coordinates and set up the equation 
For the coordinates (0,2) and (2,8) y2 is 8 and y1 is 2. x2 is 2 and x1 is 0. 
you have to do subtraction first. 8-2 = 6 and 2-0 = 2
Now we have the equation 
this can be simplified to
Answer:
7.5 feet long
Step-by-step explanation:
if I had one, 5 foot sandwich, I would have 8 pounds. if I had 2.5 more foot of sandwich I would have 4 more pounds ( because 2.5 feet is half of 5 feet which means we would have to divide 8 pounds by 2). which means I have 8 pounds and 4 pounds, which equals 12 pounds. I also have 5 feet and 2.5 feet of sandwich which is equal to 7.5 feet. since it's asking the length of a 12 pound sandwich, your answer is 7.5 feet long.
Answer:
x = 18
Step-by-step explanation:
5/6x = 15
Multiply each side by 6/5 to isolate x
6/5 * 5/6 x = 15 *6/5
x = 15/5 *6
x =3*6
x = 18
4b+3s=72
6b+3s=96
Multiply the second equation by -1
-6b-3s=-96
Now you can cross out the +3s -3s
-2b=-24
Divide both sides by -2
b=12
s=8
So blouses cost $12 each and skirts cost $8 each
