How Do You Solve for Variables in Algebraic Equations?

Click For Summary
To solve for variables in algebraic equations, it's essential to manipulate the equation to isolate the desired variable. Participants emphasize the importance of showing work to receive assistance, as help is contingent on demonstrating understanding. Basic algebraic skills are necessary, and familiarity with algebra is recommended for effective problem-solving. The thread was locked due to the original poster not providing any work for review. Clear communication and effort in showing calculations are crucial for receiving help in algebraic problems.

Homework Equations





The Attempt at a Solution


well all we have to do is sove for the variable indicated...but i really don't understand how to solve for the variables..lol, just basic high school physics. maybe I'm thinking too hard, but i seriosly need some help guys :( i solved a few of them, but idk if they're right, lolol :P i'd really appreciate it if you could also show your work! haha

You will not get any help if you don't show your work. Post your results and someone may help you if there are any errors.
 
Have you studied algebra yet? All you are asked to do is manipulate the given equation to solve for the indicated variable. You don't need to know what the equation is for.
 
Thread locked, due to no work shown by OP.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
