Answer:
8 5/6 -> 8.839 -> 177/20 -> 8.99
Step-by-step explanation:
8 5/6 = 8.333
8.839
177/20 = 8.85
8.99
18 - 2 = 16
8n = 16
Divide
N = 2
Answer:
3/5
Step-by-step explanation:
sin is opposite divided by the hypotenuse ( longest side)
18 is the opposite of angle x and the hypotenuse is 30
18/30 = 3/5
Answer:
The solution of this system of equations is (3 , -8)
Step-by-step explanation:
The given system is
x + 2y = -13
12x + 5y = -4
We make x the subject of the first equation and put it into the second:

We put this expression for x into the second equation
12(-13-2y)+5y=-4
-156-24y+5y=-4
-24y+5y=-4+156
-19y=152
y=-8
We substitute y=-8 into x=-13-2y to get:

The solution of this system of equations is (3 , -8)
