In order to find "r", you need to isolate it. So in order to isolate it, you do the inverse operation. In this case, it would be division because 0.3 is being multiplied by "r". So you divide by 0.3 on both sides to get 7.
To solve this problem you will need to find the volume of the soup can (cylinder).
Volume of a cylinder: 
Plug 2 for r and 4 for h.
= 50.24 (using 3.14 for pi)
50.24 in³ of soup will fit in the can.
Answer:
-6.2, -3.1, -1.55, -0.775, -0.3875...this is not an arithmetic sequence
Step-by-step explanation:
Solution for F(x)=6x^2-900 equation:
<span>Simplifying
F(x) = 6x2 + -900
Multiply F * x
xF = 6x2 + -900
Reorder the terms:
xF = -900 + 6x2
Solving
xF = -900 + 6x2
Solving for variable 'x'.
Reorder the terms:
900 + xF + -6x2 = -900 + 6x2 + 900 + -6x2
Reorder the terms:
900 + xF + -6x2 = -900 + 900 + 6x2 + -6x2
Combine like terms: -900 + 900 = 0
900 + xF + -6x2 = 0 + 6x2 + -6x2
900 + xF + -6x2 = 6x2 + -6x2
Combine like terms: 6x2 + -6x2 = 0
900 + xF + -6x2 = 0 </span>
