Answer

Answer:

6

Explanation:

Step1: Set up equation

The total amount of salt in the mixture is the sum of the salt in each solution. So, (0.1 + 0.09x=0.64).

Step2: Isolate term with (x)

Subtract (0.1) from both sides: (0.09x=0.64 - 0.1), which gives (0.09x = 0.54).

Step3: Solve for (x)

Divide both sides by (0.09): (x=\frac{0.54}{0.09}=6).
