-3y + 7 = y - 6(¹/₂y) - 6(2)
-3y + 7 = y - 3y - 12
-3y + 7 = -2y - 12
+ 3y + 3y
7 = y - 12
+ 12 + 12
19 = y

The sine model for the height (in feet) of the end of one windmill blade as a function of time t (in seconds) is; y = 30sin(πt/15) + 30
How to solve Sine Functions?
The period of a sine function is represnted as;
b = 2π
This period is usually repeated after each 2π units.
The sine model is expressed as;
y = a(sin (bt)) + k
We are told that the blades are 10 feet long and complete 2 rotations every minute. Thus the period is;
b = (2π/60) * 2
b = π/15
The blades of a windmill turn on an axis that is 30 feet from the ground and the blades are 10 ft long. Thus,
k = 30 and a = 10
Plugging the relevant values into the given formula gives;
y = 30sin(πt/15) + 30
Thus, the sine model for the height (in feet) of the end of one windmill blade as a function of time t (in seconds) is;
y = 30sin(πt/15) + 30

Your question isn't really clear. Let me help you rephrase it and solve.
Let's say Cesar is creating a schedule to practice his instrument for band. He needs to practice for a total of 10 hours in a week. On Monday he practice for 1 1/2 hours, on Tuesday he practiced for 2 1/4 hours, and on Wednesday he practiced for 1 1/2 hours.
The total hours that Cesar has used in practicing will be:
= 1 1/2 + 2 1/4 + 1 1/2
= 5 1/4
To get the number of hours that Cesar need to practice during the rest of the week in order to have his 10 total hours, we subtract 5 1/4 hours from 10 hours. This will be:
= 10 - 5 1/4
= 4 3/4 hours.
Cesar needs to practice for 4 3/4 hours more.
