Answer:

w = 5/7

Step-by-step explanation:

We move all terms to the left:

15/7-(3w)=0

We multiply all the terms by the denominator

-3w*7+15=0

multiply elements

-21w+15=0

We move all terms containing w to the left, all other terms to the right

-21w=-15

w=-15/-21

w=5/7

You roll a standard number cube 36 times, how many times can you expect to roll an odd number?
Xelga [282]

Answer:

18 times

Step-by-step explanation:

Half of the possibilities you can roll are correct. so 18 out of 36 times you roll an odd number.

You could also look at it another way. You can expect to roll each number 6 times, so the 3 odd numbers added together is 18 times.
