15x + 5y = 5

3x + y = 1

15x + 5y = 5 \\ 3x + y = 1 \\  \\ 15x + 5y = 5  \\  - 5(3x + y = 1) \\  \\ 15x+5y=5 \\  - 15x - 5y =  - 5\\  -  -  -  -  -  -  -  -   \\0   + 0 =  0 \\   \\

this has an infinite number of solution. (0 = 0)

in graph, this is an overlapping lines

What is the volume of a sphere with diameter of 4 millimeters
marin [14]
The volume is 33.5mm^3 (or cubed)

Formula : v = 4/3πr^3 or v = 4 x 3.14 x (r x r x r) <span>÷ 3
</span>
~ 2 x 2 x 2 = 8  (we use 2 because the radius is half of the diameter)

v = 4 x 3.14 x 8 <span>÷ 3     a. Multiply everything together
v = 100.48 </span><span>÷ 3             b. Divide by 3</span><span>
v = 33.493                   c. Round (if needed)
</span>v = 33.5
