Answer:
83%
Step-by-step explanation:
We can put this into a fraction to get the ratio of the new price over the old price

This will give us the percentage of how much was decreased.
The answer you get is .83
Bring 2 decimal places to the right to get 83 (converting from decimal to percentage)
You get 83 percent to be your answer
Answer:
L = 15
Step-by-step explanation:
P = 2L + 2W
you know that P = 50, W=10
So you have to replace those values on the equation
50 = 2L + 2*(10) --> Replace P and W
50 = 2L + 20 --> Multiply and now you are going to separate the unknown and the constants.
Remember that if you send a constant to the other side of the equal the sign will change to its opposite
50 - 20 = 2L --> Solve the constants
30 = 2L --> Now for the L, you have to leave it alone, so the 2 that is multiplying you have to send it to the other side of the equal but with the opposite operation, the opposite operation of multiplying is dividing, so you have:
30/2 = L
L= 15
Answer:
7.5 m
Step-by-step explanation:
