Answer:
Step-by-step explanation:
<u>Let the number is x, then we have:</u>
- 6x - 19 = 4x + 11
- 6x - 4x = 11 + 19
- 2x = 30
- x = 15
Answer: 13 packages.
Step-by-step explanation:
This can be translated to:
Tim has 39 pairs of headphones and 13 music players. Tim wants to sell all the headphones and music players in identical packages. What is the largest number of packages that Tim can do?
To solve this we must find the largest common factor between 39 and 13.
to do this, we divide the smaller number by different integers, and see if the result also divides the larger number into an integer.
13/1 =13 and 39/13 = 3
So 13 is the largest common factor.
This means that we can make 13 packages, each with:
39/13= 3 headphones
13/13 = 1 music players
Answer:
D. Alice used empirical probability, Mark used theoretical probability.
Step-by-step explanation:
Alice used empirical probability because she actually flipped the coin 100 times but Mark assumed the coin was fair and didn't actually test it, using theoretical probability.
Y=3
Simplify
Distribute
Combine like terms
Add 2y to both sides
Add 2 to both sides
Divide by 3 , both sides.

Answer:
9/10
Step-by-step explanation:
you find the lowest common denominator in this case is 10
then you take 1/2 and multiply it by 5 both the bottom and top and then you should get 5/10
next you do the same with 2/5 but this time to the get the denominator to 10 you multiply by 2 again multiply both bottom and top and you should get 4/10
now you just add 4/10 and 5/10 together and you get 9/10 or 0.9 as a decimal
