Answer:
x=2
y=1
Step-by-step explanation:
2x+y=5
3x+2y= 8
<=> 6x+3y=15
6x+4y=16
<=> -y=-1
<=> y=1
2x+1=5
2x=4
Surface Area of a Sphere is...
Now...
The answer is Option C
.20
3/15 -- lets simplify
3/15 = 1/5, which is 20% or .20
I think that it's 30 or 22 because there is a high chance
Cos(65°) = √(1 + cos(130°)) / 2
0.42=√(1 - 0.64)/2
0.42=√(0.36)/2
0.42²=√0.18²
