So you make them into an improper fraction with a common denominator. so it would be 18/4 - 7/4, and it equals 11/4, or 2 & 3/4!
Answer:
16/21
Step-by-step explanation:
A, 10. b,-300. c, -1. d, -3567.
youre basically looking for the number that gets you to the other number. how far away from 30 is 40? 10. how far is 500 from 200? 300, but in the other direction so its negative. and for D since the final number is 0 just use the same number but flip the sign
TanY=y/x
cotY=1/tanY
cotY=x/y
