In order to solve an equation for a variable, we need to isolate that variable on one side of the equation (either left side or right side).
Following are some steps to solve equation/inequality in one variable:
1) Get rid constant number from on side by applying reverse operation of addition or subtraction.
2) Get rid variable terms from other side by applying reverse operation of addition or subtraction.
3) Combine like terms on both sides.
4) Get rid any coefficent ( a number in front of a variable) by dividing from both sides.
5) Finally you get a variable on one side and solution on other side.
From question given
Radius r = 5.5 ml
Volume = ?
We know that
Volume = The formula is 4/3 × π × radius3.
= 4/3 × 3.14× 5.5^3
= 696.557 ml^3 answer

Answer:
Option B. For every 5 red pens, there are 15 blue pens.
Step-by-step explanation:
The statement expressed the ratio of the red pens to the total as 1 : 4.
This means that for every red pen in the box, there are 4 blue pens.
So, statement A is correct.
Let's skip B an look at other statements as well:
For C, the ratio will be 15 : 60 which translates to 1 : 4. So C is true.
Let's look at D.
This is an interesting one. The problem defines 18 as blue. So it means that 24 - 18 = 6
6 pens will be blue. Again 6 : 24 gives us 1 : 4. So D is true.
B gives us 5 : 24 which is not true.
