Jake completed a cube puzzle in 8.352 minutes. what is the number written in expanded notation?

First you need to be able to identify what place each number is in.
The 8 is the whole number, so the ones place. The 3 in the tenths. The 5 in the hundredths. The 2 in the thousandths. 

Now, you can expand. 

(8 + .3 + .05 + .002) 

Because we identified what place each number was in, when we expanded the number, we knew where to put the number and to fill in the empty places with zeros.

I hope you understand it the way I tried to explain ! (:

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
