A + 2K = 8.75
2A + 5K = 19.75
Change the first expression so that we can subtract the As
2A + 5K = 19.75
2A+4K= 17.50
If the signs are the same, subtract one expression from another
K= 2.25
substitute K into any expression to get A
A+4.50= 8.75
Subtract 4.50
a=4.25
K=$2.50
A= $4.25
-720 because counter clockwise it would be 720 which is 360 times 2 but since it is backwards it’s -720.
It’s 120%
6/5 is 1.2. Multiply by 100 to get a percent.
