All you wanna do is get 'y' by itself so you divide 80 by -5 and you get -16 as the answer
27+15 is 2 so anything that is equal to 42 is equivalent to 27 +15
Answer:
B = 129
Step-by-step explanation:
Opposite angles of a parallelogram are equal (or congruent)
A and C are both 51.
All angles in a parallelogram equal 360
Take both the known angles and substract from 360, than divide by 2.
B = (360 - 51 - 51)/2
B = 129
12/6 +7 *2 =16 if you just plugin the variables
