If the price of an item has been reduced by 65%, that means that it used to be 35% higher, and that is the number we have to use in the equation. Here it is:
x - price
35% - how much it got discounted
60 - new price
100% - total percentage
x : 35 = 60 : 100
100x = 60*35 (crossover multiplication)
100x = 2100
x = 2100 / 100
x = 21
The price of the item now is 21$.
Or you can do it this way:
65% of $60 = 0.65 of 60 = 39; 60 - 39 (how much it was discounted) = 21 (the new price)
15% is equal to 15/100 or .15
To find a part of a number, multiply the decimal form of the percentage by the number, or 60* 0.15. The answer is 9

Step-by-step explanation:
The drag force is described as the force experienced by an object due to movement through a liquid. In this case it is water. The equation used for drag force F is:
the density of water is p=1000 kg/m³. We know that F=0.5 N.
The speed is 0.032 m/s
Answer:
The equation is 39=3r-6
Step-by-step explanation:
Let x = # of years from the start of the Great Depression to the first Presidential election of Nixon
Let r = Raul's age
The question gives us what x equals so...
x=39
Now we just turn the sentence into an equation.
"The number of years from the start of the Great Depression to the first Presidential election of Nixon [(x)] is six years less than three times Raul's age [(3r-6)]"
Remove the icky words...
x=3r-6
replace x with what it equals (39)
39=3r-6
Now you can go on to olve it
Overal Raul is only 15 :)
