Solving Equations: Help for Math-Rusty Students

In summary, to solve the equation (30m/s - 10m/s)/2.0s = 10m/s^2, you need to first subtract the initial velocity from the final velocity and then divide the result by the time. This will give you the acceleration, which is represented by the units m/s^2. Remember that when dividing fractions, you need to flip the second fraction and multiply. This will give you the final answer of 10m/s^2.

I haven't had any math in like 4 years and I'm very rusty. Could someone please show me a "step by step" how to solve an equation like this...

(30m/s - 10m/s)/2.0s = 10m/s^2

I forgot how to get to the answer.This example came from my book. Can someone please explain how the answer became 10m/s^2 ?



I got lost with the metere/second square

Please help

Thanks in advance.

[tex]\frac{(30m/s - 10m/s)}{2.0s} = [/tex]

[tex]\frac{(20 m/s) }{ 2s} = [/tex]

[tex]\frac{20}{2}\frac{m/s}{s} = [/tex]

[tex]10 \frac{m}{s}\frac{1}{s}=[/tex]

[tex]10\frac{m}{s^2}[/tex]


Remember: [tex]\frac{a}{b}/c=\frac{a}{b*c}[/tex]

FAQ: Solving Equations: Help for Math-Rusty Students

How do I know which operations to use when solving an equation?

The key to solving equations is to always maintain the balance on both sides of the equation. This means that whatever operation you perform on one side, you must also perform on the other side. For example, if you add 5 to one side, you must also add 5 to the other side.

What is the order of operations when solving equations?

The order of operations when solving equations is the same as the general order of operations in math: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

How can I check if my solution to an equation is correct?

To check if your solution is correct, simply plug the solution back into the original equation and see if it makes both sides of the equation equal. If it does, then your solution is correct.

What do I do if there are variables on both sides of the equation?

If there are variables on both sides of the equation, the goal is to isolate the variable you are solving for on one side of the equation. You can do this by using inverse operations to cancel out the variables on the other side.

How can I improve my skills in solving equations?

The best way to improve your skills in solving equations is through practice. Start with simple equations and gradually move on to more complex ones. You can also seek help from a tutor or use online resources such as tutorials and practice problems to improve your understanding and skills.
