I hope this helps you
x=y+4
3 (y+4)+y=8
3y+12+y=8
4y= -4
y= -1
x= -1+4
x=3
(3, -1)
Answer:
k=45
Step-by-step explanation:
Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that
. 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have
. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides
as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.

Step-by-step explanation:
x be an irrational number between 9.5 and 9.7.
So, we consider that x = 9.562536941412578914...
Rounding to the nearest hundredth
x = 9.56.
9.56763865854637984..... (rounded 9.57)
irrational because it has no pattern
