Solving 0.80p = 320

solving for variable p

move all terms containing the p to the left , all other terms to the right

divide each side by 0.80
p = 400

Simplifying
p = 400

Hi there!

Answer:

p=400

*The answer must have a positive sign.*

Explanation:

Lesson: Using Properties to Simplify Expressions

Distributive property: →→→
a(b+c)=ab+ac

First, you multiply by 10 from both sides of an equation.


0.8p*10=320*10

Then, you refine. You can also multiply by the numbers from left to right.


8p=3200

Next, you divide by 8 from both sides of an equation.


(8p)/(8)=(3200)/(8)

Finally, you simplify and solve. Divide by the numbers from left to right.


3200/8=400

Final answer is p=400

I hope this helps you!

Have a nice day! :)
