15 tickets are yours.
250 * .06 = 15
You move the decimal point 2 places to the left because .6 is 60% instead of 6%
Answer:
The solution to the set of linear equations is:

Step-by-step explanation:
Hey there!
In order to solve this system of equations, we can put the equations equal to each other since both equations are equal to y

Now we simplify
---> 
So now that we know that x is equal to 5, we can find the value of y
let's substitute it in one of the equations
---> 
So now we know that the point where the two equations intersect is:

This is going to be our solution

8 hours is twice as many as 4:
Multiply the number of windows in 4 hours by 2:
32 x 2 = 64 windows in 8 hours
Answer:
y=-48
Step-by-step explanation:
y/6 - 3+3=-11 + 3 add 3 to both sides
y/6=-8 simplify
6y/6=6(-8) Multiply both sides by 6
y=-48
Multiply 2/5 by 2 to get 4/10
4/10 + 3/10 = 7/10
