Hello.

For all dilution problems use the dilution equation:
C1V1 = C2V2 
20*V1 = 6*55 
V1 = 6*55/20 
V1 = 16.5 gallons 
The final volume must be 16.5 gallons 
You must add 16.5 - 6 = 10.5 gallons water to be added.

Have a nice day

Consider the following Function: F(x)= 7x-9 If the output is 26, what is the input?

Wewaii [24]

<h2>Answer:-</h2>

★ Input of the given function F(x) is 5.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>• Given:-</h3>

✯ F(x) = 7x - 9

✯ Output = 26

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>• Solution:-</h3>

According to the question the output is 26.

Hence, the above data can be written in an equation form.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ F(x) = 7x - 9 = 26

➪ 7x = 26 + 9

➪ 7x = 35

➪ $\sf x = \dfrac{35}{7}$

➪ $\bold\red{x = 5}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, F(x) = 5
