12 divided by 3 is 4 witch means he goes 4 miles every day
4 times 20 is 80
so I think it takes him 20 days to reach 80 miles
Answer:
20 days
Step-by-step explanation:
3days/12mi = 4 miles per day
80/4= 20 days
it is 100
78
6*10=60
2*9=18
60+18=78
The value of x=4.5
4.5+x=9
or, x=9-4.5
or, x=4.5
3n+2=5n=8
n=8÷5
n=1.6
