Answer: 49 and 38
Step-by-step explanation:
I did trial and error
38+11=49
49+38=87
You would combine the like terms to get -9c
13/20= 0.65
3/4=0.75
4/10=0.4
5/8=0.625
So the right order is 4/10, 5/8, 13/2, 3/4
First set the days to hours. Since there are 24 hours in a day you can do 197 x 24 = 4728 hours. Take the distance (48688630 miles), to get to miles per hour you do 48688630 : 4728 = 10297,933 = 10298 so B is the answer.
(10^4)^2 = 10^(4*2) = 10^8
1 metric ton = 10^8 = 100,000,000 grams.
