Answer:
The number of hours did Sarah practice more than Leilani is 
hours .
Step-by-step explanation:
Given as :
The time for which Leilani practiced piano = 
hours
The time for which Sarah practiced piano = 
hours
Let the number of hours did Sarah practice more than Leilani = T hours
<u>Now, According to question</u>
The number of hours did Sarah practice more than Leilani = hours - hours
Or, T = 
hours
Or, T = hours
So,The number of hours did Sarah practice more than Leilani = T = hours
Hence, The number of hours did Sarah practice more than Leilani is hours . Answer

Step-by-step explanation:
a parallelogram has sides that are parallel to the opposite side. This means that y + 7 is going to be parallel to 20.
Two opposing sides of a parallelogram are parallel and equal
You know that the length of both of the sides is equivalent because the other set of opposing lines is also parallel (you can think of it as cutting off the line segment of y+7 and 20 at the same length. )
this means that we can set up the equation to find y as:
y + 7 = 20
then, you can proceed to find y by isolating it:
y + 7 = 20 ; so therefore
y + 7 = 20
- 7 -7
y = 13
y = 13
So, the value of y is 13
