While converting a number to scientific notation, if you move the decimal point three places to the right, then the exponent that you use for the 10 will have a negative sign.
a. true
b. false

1000.000*10^0
move to right 3 places
1000000.010^-3
true because you ah ve to compensate for the movement
when move right, minus exponent
when move left, add exponent

true

A. true

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!
