Answer:
5
Step-by-step explanation:
8(3 + a) = 64
3 + a = 8
a = 5
Ben - 3/8
RV - 1/8
Total = 80
Ben = 3/8 ( 80 ) = ( 3 ) ( 10 ) = 30 cars
Rv = ( 1 / 8 ) ( 80 ) = ( 10 ) = 10 cars
Ben's have sold 20 cars more than RV

That number in scientific notation is 1.26 x10^-5. The decimal up front has to be greater than 1, but less than 10. We move the decimal to the left to get that answer 5 times. That is what gets us 1.26 x10^-5.
She bought 12, so there is a total of 12 grams.
If she ate half of it, you divide by 2.
12/2= 6 grams
