The numbers DO differ by 10 if they are
- 1 and 11
- 2 and 12
- 3 and 13
- 4 and 14
- 5 and 15
Each outcome technically has two ways of occurring, but since we're taking two marbles at a time, that would be the same as saying, for instance, that drawing 1 and 11 is the same as drawing 11 and 1. We only count such an event once.
So the answer is (a) 5.
Answer:
Step-by-step explanation: since average speed = total distance/time
a)average speed of the journey from my home town to A = 10 miles/20 minutes = 0.5
b)journey from my home town to B = 20 miles/30 minutes = 0.7
c)10 miles + 20 miles = 30 miles
which takes 50 minutes
so: 30 miles/50 minutes = 0.6
If you look at the model RM is the same length as PM. PM=10 so RM=10.
Answer:
Step-by-step explanation:
34=-11+7A
We move all terms to the left:
34-(-11+7A)=0
We add all the numbers together, and all the variables
-(7A-11)+34=0
We get rid of parentheses
-7A+11+34=0
We add all the numbers together, and all the variables
-7A+45=0
We move all terms containing A to the left, all other terms to the right
-7A=-45
A=-45/-7
A=6+3/7
