1. What does the expression s/4 represent? 2. What is the solution to the equation s/4=14? 3. Consider the pan balance. What would happen if you replaced the 8-ounce weight with a 10-ounce weight? 4. Supposed you change one of the 4-ounce weights to a 7-ounce weight. How much weight would you have to add on the right side to make the pans balance? How do I explain it?1.

Explanation / Answer
Hello,
Sol 1) Here, s is any variable. So s can take any value. The expression s/4 represents that variable s is divided by 4 and that is the answer.
Sol 2) s/4 = 14
Here, The solution to this equation is s = 14*4 = 56.
Hence, s = 56 is the solution of the equation.
Sol 3) In a pan balance, you need to put weights on both sides. Hence, it is level when there is 8 ounce weight on both sides. But when we replace one 8 ounce weight with 10 ounce weight, then it weighs more on 10 ounce weight and it gets down on its side.
Sol 4) If i replaced 4 ounce weight with 7 ounce weight on one side, then i will need to add 3 ounce weight on the other side to make the pans balance. This is because 3 ounce got increased on the side where we replace 4 with 7 ounce weight. Now to balance it, we need to add 3 ounce weight on other side.
Thanks
