Answer:
Step-by-step explanation:
3 times 60 = 180 minutes
10 * 60 = 600 minutes
600/20 = 30 * 3 = 90 hours
Answer:
X=-4, Y=22, idk about the CBD
Step-by-step explanation:
4y+2=90 degrees
subtract 2 on both sides you would get
4y=88 divide 4 with 88 and get 22
solve both X's so 5x+6=3x-2
i would subtract 3x first so i can get
2x+6=-2
then subtract 6 on both sides so you would have
2x=-8 divide -8 with 2 and get -4
For this case we must solve a system of two equations with two unknowns, given by "x" and "y".
We have:

We multiply (2) by -1:

We add (1) and (3):

Clearing x:

We substitute
in (2)

Thus, the solution of the system is 
Answer:
The solution of the system is
