The distributive property (the 5 is distributed to both the x and -7)
Answer:
120 x 10^-4
Step-by-step explanation:Multiplying 1.2 by 10^2 and multiplying 10^-2 by 10^-2.Gives 120 x 10^-4 So, the mass of an average grain of rock salt is 120 x 10^-4 .
30×·15=4.50
then subtract 30 by 4.50 to get 25.50
.0825×30=2.475
now add 2.475+25.50+30= 57.975 round to 57.98
I believe your answer would be C. Hope this helped!
