Answer:
x=51.50-8y eqn (i)

from eqn (i) and (ii)

206-32y=39.50-y
166.5=7y
y=23.78
now putting the value of y in eqn (ii) we get
x=3.93
Answer:

Step-by-step explanation:
Simple formula:
where
is the angle in radians, and
is the angle in degrees. By plugging numbers you'll get the result.
Another way to get the result, which I like more, is to think of it in parts of the whole circle. 300° is 5/6 of a circle, and a circle measures
Hence, you want 5/6 of
, or 
Answer:
Step-by-step explanation:
4x + 3y = 24
4x - y = 8
4x + 3y = 24
-4x + y = -8
4y = 16
y = 4
4x - 4 = 8
4x = 12
x = 3
(3, 4)
Answer:
32
Step-by-step explanation:
384/960 = 4/10
4/10 x 8 = 32 / 80
