Answer:
86
Step-by-step explanation:
This is because the angles should add up to 180. So 32 + 64 is 96. Then you subtract 96 from 180 to get 86.
Answer:
the answer is 4k^2+9k+108
Step-by-step explanation:
Answer:
3/4.
Step-by-step explanation:
36 and 48 have a common factor of 12.
(36 / 12) / (48 / 12)
= 3/4 (answer).
If it’s to be solved in terms of x then it would be x=(3d+9)/(d-k)
Answer:
(3,-3)
Step-by-step explanation:
First you divide 2 out of the first equation and it turns into 5x+y=12.
Then you write one on top of the other so you can add them. It looks like:
5x + y = 12
-5x + y = -18
Then you add them together and the 5x's cancel each other out and you are left with 2y = -6
So then you divide both sides by 2 and get y = -3
Then you plug -3 into the second equation because it is simpler and get -5x - 3 = -18
So then you add three to both sides and get -5x = -15
And finally you divide both sides by -5 and get x=3
