Moira needs a total of 2 1/4 hours to finish reading a book. Yesterday, she read for 1 7/8 hours. Supply the correct numbers to complete the equation that can be used to determine the number of hours, h, that Moira needs to read to finish the book.(1 point)
h+blank=blank
h + 1 7/8 = 2 1/4
Tyrell has a goal to spend 26 hours each month volunteering in a community library. So far for this month, he has volunteered for 17 hours. Write a working equation that represents the number of hours, h , that Tyrell still needs to volunteer to reach his goal for this month and solve this equation. (1 point)
h + 17 = blank
h = blank
h + 17 = 26
h = 26 - 17
h = 9
Which of the following should be done to both sides of the equation x − 3.41 = −19 to solve the value of x ?(1 point)

add 19
add 19
add 3.41
add 3.41
subtract 3.41
subtract 3.41
subtract 19
To solve for x, you should add 3.41 to both sides of the equation.
To determine the number of hours, h, that Moira needs to read to finish the book, you can set up the equation:
h + 1 7/8 = 2 1/4
To solve this equation, we need to find a common denominator for the fractions 1 7/8 and 2 1/4. Let's convert both fractions to have a common denominator of 8.
1 7/8 = (8/8 * 1) + 7/8 = 8/8 + 7/8 = 15/8
2 1/4 = (8/8 * 2) + 1/4 = 16/8 + 1/4 = 17/8
Now, the equation becomes:
h + 15/8 = 17/8
To solve for h, we subtract 15/8 from both sides:
h = 17/8 - 15/8
h = 2/8
h = 1/4
So, Moira needs to read an additional 1/4 hour (or 15 minutes) to finish the book.
The completed equation is:
h + 15/8 = 17/8.
