maria has to spend 5 1/2 hours to finish her community service program in a community health clinic. Last week she was able to spend 3 3/4 hours. Which equation can be used to determine the number of hours, h, that maria still needs to spend to complete her service program?

The equation that can be used to determine the number of hours, h, that Maria still needs to spend to complete her service program is:

h = 5 1/2 - 3 3/4

To determine the number of hours, h, that Maria still needs to spend to complete her service program, we can subtract the hours she has already spent from the total hours required.

The equation that can be used is:
h = Total hours required - Hours Maria has already spent

Given that Maria needs to spend 5 1/2 hours to finish her community service program and she has already spent 3 3/4 hours, the equation becomes:
h = 5 1/2 - 3 3/4

Now we need to convert the mixed numbers to improper fractions:
h = 11/2 - 15/4

To subtract the fractions, we need to find a common denominator, which is 4:
h = 22/4 - 15/4

Subtracting the fractions:
h = (22 - 15)/4
h = 7/4

Therefore, the equation that can be used to determine the number of hours, h, that Maria still needs to spend to complete her service program is h = 7/4.

To determine the number of hours, h, that Maria still needs to spend to complete her service program, you can subtract the hours she has already spent from the total hours required.

The equation that can be used is:

h = Total hours - Hours already spent

In this case, the total hours required for Maria to complete her service program is 5 1/2 hours. Remember that 1/2 is the same as 2/4, so 5 1/2 can be converted to an improper fraction as 11/2.

Now, we can substitute the values into the equation:

h = 11/2 - 3 3/4

To perform the subtraction, we need to get the fractions to have a common denominator, which in this case is 4.

Converting 11/2 to have a denominator of 4, we get 22/4.

Now, we can subtract the fractions:

h = 22/4 - 15/4

Subtracting the numerators, we get:

h = 7/4

So, Maria still needs to spend 7/4 hours to complete her service program.
