Answer: 5</h3>
Explanation:
Plug z = 9 into the second equation and solve for x.
x/z = 2/3
x/9 = 2/3
x = 9*(2/3)
x = 18/3
x = 6
This leads to
xy = 30
y = 30/x
y = 30/6
y = 5
Answer:
hi there is that something you can block
I would make both denominators the same, and the lowest one that works is 18. So I'd make 1/9 into 2/18, and 1/6 into 3/18. They already used these times so combine them to make 5/18 then subtract that from the total time they had (18/18) and you would get 13/18 they spent playing music.
H= -1 here's why:
7 = 12 + 5h
First you subtract 12 from both sides then the equation would look like:
-5 = 5h
Then you would divide the equation by 5 from both sides it would then look like:
-1 = h
Answer:
a. 256
b. 255
Step-by-step explanation:
If a set has “n” elements, then the number of subset of the given set is 
and number of proper subset is 
A = {3, 4, 5, 6, 7, 9, 10, 11}
Here, n = 8
No of subsets
No of proper subsets
=
