Science-

A 25N object is 3 meters up. How much potential energy does it have? our teacher said that the formula for finding out potential energy is PE = Mass * Gravity * Height. The gravity on Earth is always 9.8, but my problem is that instead of mass the object is measured in force. My answer is 735 j.

Math-

5ãx - 30 = 2ãx + 54. I have to solve for x. So far, I think this is wrong, but I have added 30 to both sides and I solved to get x = 4. Thanks.
