Solve for x.

The answer is 370 because you need to work it out.

Basically what I did was look at the first number, 12, and the answer to the equation and saw that 12 x 10 would be 120. And 360 + 10 would be 370.

It fits in perfectly.

12(370 - 360) = 120
370 - 360 = 10
12(10) = 120

So x = 370

Jun used x milliliters, or 90% percent, of his favorite bottle of hot sauce.
Verizon [17]

Answer:

The volume of the full bottle of Jun's favorite hot sauce in ml is \frac{10x}{9}.

Step-by-step explanation:

Jun used x milliliters, or 90% percent, of his favorite bottle of hot sauce.

So, to find the volume of a full bottle of Jun's favorite hot sauce in milliliters, we can use the unitary method.

Then, 90% of the full bottle sauce is equal to x ml.

So, 1% of the full bottle sauce is equal to \frac{x}{90} ml.

Therefore, 100% of the full bottle sauce is equal to \frac{x}{90}\times 100 = \frac{10x}{9} ml.  

Therefore, the volume of the full bottle of Jun's favorite hot sauce in ml is \frac{10x}{9}. (Answer)
