The volume of premium antifreeze to be used is 60 gallons.
The volume of water to be used is 120 gallons
<h3>What is a percentage?</h3>
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Let the volume of 60% pure antifreeze be used to make 20% pure antifreeze.
= x gallons
The volume of 20% pure antifreeze = 180 gallons
For 60% pure antifreeze:
C₁ = 60% , V₁ = x gallons
For 20% pure antifreeze :
C₂ = 20% , V₂ = 180 gallons
Applying,
C₁V₁ = C₂V₂
60 × x = 20 × 180
x = 60 gallons
The volume of 60% pure antifreeze used = 60 gallons.
The volume of water to be used.
= 180 - 60 gallons
= 120 gallons
Thus,
The volume of premium antifreeze to be used is 60 gallons.
The volume of water to be used is 120 gallons

The value of x is 8
- This question is a proportion. To solve it, let's assemble it as follows:
<u>5</u> = <u>4</u>
10 x
- Now, just multiply in the form of a cross. Then, let's split the terms:
5 . x = 10 . 4
5x = 40
x = 40 ÷ 5
<u>x = 8</u>
So, the result of x will be 8
