The answer is 9. 7 times 9 is 63 and then 63 divided by 3 is 9.
Answer:
4:1 (I think)
Step-by-step explanation:
Let's write some equations first:
For both prices increasing by 20:

then we can use cross multiplication
2x+40=5y+100
For both prices decreasing by 5:

same here:
5y-25=x-5
Using substitution for 5y, we get: 5y=x+20
2x+40=5y+100
2x+40=x+20+100
x=80
plugging this in to the second equation:
5y-25=x-5
5y-25=80-5
5y-25=75
5y=100
y=20
therefore we get x:y=80:20
4:1
Answer: y = -3/4x - 15/16
Step-by-step explanation: Write in slope-intercept form, y=mx+b.

0.5(y + 3.3)
The product of 0.5 and the sum of y and 3.3.
0.5 times the sum of y and 3.3
Answer:
(1, 3)
Step-by-step explanation:
The first number of each pair is the x-coordinate, the horizontal location of the point.
The end points of the graphed line segment are (1, 3) and (-3, -2). It looks like the answer choices are intended to see if you can tell what order the coordinates are expressed in.
The appropriate choice is (1, 3), the upper right end point.
