They both have the same amount of CDs
bc 6 country Cds plus another 6 country CDs is 12 Cds. 5 rock Cds plus 5 rock CDs is 10 rock CDs. so in total they have 22 CDs
While the question gives us the coordinates for 4 points, we only need 2. You can choose any pair of points and the process I will demonstrate will still be applicable and you will get the same results. I will just pick the first two points.
Points: (4,-4) and (8,-1)
As you may already have known, the first number in the parentheses is the x value and the second number is the y value. In order to solve for the slope of the line created by the two points, we must find the difference between the y values of the two points and divide by the difference between the x values of the two points. This can more commonly be called delta y over delta x.
(y of point 1 - y of point 2)/(x of point 1 - x of point 2)
= (-4 + 1)/(4 - 8)
= (-3)/(-4)
=3/4
Slope = 3/4
If how much owen saves is x, 2x=y (jessie's amount of saved money) and
x-5=nick's amount of money =z
Since x+y+z=220, we plug 2x in for y and x-5 in for z, getting x+2x+x-5=220. Adding 5 to both sides, we get 4x=225 and by dividing by 4 we get x=225/4=61.25 dollars. 61.25-5=56.25=z=nick's money, and 61.25*2=122.5=jessie's saved money
Answer:
bxcdxdbdbdbdxxbdxdbbxd
Step-by-step explanation:
If you divide 189 by 8 you would get 23.625 but first you have to subtract 13 from 189 (176) then divide it (22) the answer is 22 dollars
