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?(1 point) Responses h − 512 = 334 h minus 5 and one-half equals 3 and three-fourths h + 512 = 334 h plus 5 and one-half equals 3 and three-fourths h + 334 = 512 h plus 3 and three-fourths equals 5 and one-half h − 334 = 512 h minus 3 and three-fourths equals 5 and one-half
h + 3 3/4 = 5 1/2
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 + 3 3/4 = 5 1/2
To determine the number of hours, h, that Maria still needs to spend to complete her service program, you need to subtract the number of hours she has already spent from the total number of hours required.
The total number of hours she needs to spend is 5 1/2 hours, which can be written as 5.5 hours.
The number of hours she has already spent last week is 3 3/4 hours, which can be written as 3.75 hours.
So, the equation that can be used is:
h (number of hours she still needs to spend) = total number of hours - number of hours spent
h = 5.5 - 3.75
Simplifying the equation:
h = 1.75
Therefore, the correct equation to determine the number of hours, h, that Maria still needs to spend to complete her service program is:
h = 1.75
