Substitute y = -x into the first equation:
-8x - 7(-x) = -5
-8x + 7x = -5
-x = -5
x = 5
Substitute x = 5 into y = -x
y = -(5)
y = -5
Answer: x = 5, y = -5
By definition, the volume of a sphere is given by:
V = (4/3) * (pi) * (r ^ 3)
where,
r: radius of the sphere.
Substituting we have:
V = (4/3) * (pi) * ((3) ^ 3) = 113.08 in ^ 3
answer
the best estimate for the volume of air in the balloon in cubic inches is
C. 113.1
Answer:
Step-by-step explanation:
If that is a square, then all sides are the same. Therefore, it's a 
by shape. We'll use Pythagorean Theorem to find the diagonal.
Since it's not a fraction, there is no denominator to rationalize. Let me know if you have any other questions!
The expression 0.15(x-350) would be the proper equation.
