I think it's 12x.
I'm not a 100% sure though, but I hope this helps. =^D
Answer:
Let's begin with a 30°-60°-90° triangle. A 30°-60°-90° triangle with a hypotenuse of 2 um
Step-by-step explanation:
This is correct, because it takes 27 minutes to get home so it will probably be about 30 minutes.
Answer:
18x + 13y = 60
6x + 2y = 6 ---> 6x = -2y +6 ---> 18x = -6y+18
Substitution
(-6y +18)+13y =60
-18 -18
--------------------------
7y = 42 so y=6
Then, 6x + 2(6) =6, which you will get x = -1
(-1, 6)
