5/4 because the numerator and denominator are both divisible by 3
It just has to equal 90° so that they are parallel so 16x-6=90
16x=96 (add 6 to both sides)
x=6(divide by 16)
I think its -3, -1, and 2.
3z-4=6z-17
-3z-4=-17 (subtracted the 6z from both sides)
-3z=-13 (added the 4 to both sides)
z=

(divided both sides by -3z)
z=
You would do 12 divided by 25 which equals 0.48 and keep on doing that the next one is 0.52 and last is 0.53 meaning the best is the 12 muffins
