You have a 10kg bag of sand. the mass of a grain of sand is about 10 to the -3 power gram. about how many grains of sand are in the bag of sand

10 kg* (1000 g/ 1 kg)* (1 grain of sand/ 10^(-3) g)= 10^7 grains of sand.
(Note that the units cancel out so you get the answer)

The final answer is 10^7 grains of sand.

Hope this helps~

Distance=slopeslope is -2/4which equals-1/2the distance between these two points is -1/2

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the value of x is equal to 0.
