Sqrt 11 is approximately 3.31662479036
So make a line from about -5 to 5 and just estimate where that could be, between the numbers 3 and 4, make sure you mark that that is sqrt 11
The exponent of 10x10 is 100
4/9*9/5 you have to reciprocate the 5/9 since you want to change division to multiplication.
So 36/45 is the answer
Answer:

Step-by-step explanation:
Since you want to get q only and q appears in both side of the equation. Try to isolate q to one side.
1) Expand 2(q+p)
2q + 2p = 1 + 5q
2) Move all q terms to one side
5q - 2q = 2p - 1
3q = 2p - 1
3) Divide 3 on both side (to isolate q)
q = 
So 12 waters and 15 sodas makes 27 drinks total for you have a 12/27 chance of grabbing water ad 15/27 on soda<span />
