Joanne purchased a new computer for $1,700. She will need to pay $80 each month, Interest free, to pay off the total price of the computer. She plans to put $150 each month in her savings account, which currently has a balance of $300. Create an augmented matrix from a system of equations to help Joanne determine when she can pay off the total purchase price of the computer.

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
