A large container is partially filled with n liters of water. Ito adds 10 liters of water to the container, making it 60% full. If Ignacio adds 6 more liters of water, the container will be 75% full. What is the value of n?

Step-by-step explanation:

Let the total amount of water the container can hold be . Currently, there are liters in the container. If Ito adds 10 liters of water, the container will be 60% full. We can express this statement in the following mathematical equation:

Next, we're given that if we add 6 more liters to this, the container will be 75% full.

Therefore, we have:

This is a system of equations:

Subtract both equations to conveniently get rid of :

Combine like terms:

Divide both sides by -0.15:

Now substitute into any equation (I'll choose the first):

Subtract 10 from both sides:

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
