A) 6x -5y = 5
B) 3x + 5y = 4
Adding the equations:
9x = 9
x = 1
A) 6*1 -5y = 5
A) 6 - 5 = 5y
A) 5y = 1
y = 1/5 = .2
Answer:
A beach ball is a sphere, so we will need to know how to find the volume of a
sphere. V = 4Pi * (r ^ 3 / 3)
We have the diameter, but not the radius. To find the radius, it is half of the
diameter.
10÷2=5 Now let's plug it in.
4T(5³/3) Let's solve.
4pi = 12.56
5³= 125
125÷3= 41.67 (repeating 6) 41.67x12.56=523.3752
523.33 cubic inches is the volume of
air contained inside the beach ball. The reason I picked that answer is because a repeating 6. So we should expect for
we rounded up to 41.67, when there was
the answer to be a couple decimals lower
from the answer we got. Tell me if this helps!!
32 is the answer I know this really well
Answer:
x= -108
Step-by-step explanation:
x/6 + 7 = -11
x/6= -11-7
x/6= -18
x= -18*6
x= -108
