I believe that the answer you're looking for is B. h+(h+2.5)=22.
h+(h+2.5)=22
h+h+2.5=22
Combine like terms.
2h+2.5=22
Subtract 2.5 from both sides.
2h=19.5
Divide both sides by 2.
h=9.75
Now let's check the work by plugging 9.75 into the equation.
9.75+(9.75+2.5)=22
9.75+9.75+2.5=22
22=22
So we now see that the answer choice <u>B.</u> Is correct! And William worked 9.75 hours. I hope that you found this helpful!
Answer:
3/56
Step-by-step explanation:
There are 8 letters in the word DECEMBER. The probability of picking a C first is 1/8, since there's only one C. Since the letter is not replaced, there are now 7 letters to choose from, out which 3 of those are the letter E. Therefore, the probability of picking an E second is 3/7. The total probability then is equal to
times
, which is equal to
.
Hope this helps! :D
It would be D because the division symbol represents subtraction when your expanding a fraction like this one. Hope that helped.
