Mario is x years old. In 7 years, he will be 19. Which equation can be used to determine Mario’s present age?(1 point)Responsesx − 7 = 19x minus 7 equals 19x + 7 = 19x plus 7 equals 19x + 19 = 7x plus 19 equals 7x − 19 = 7
x - 7 = 19
is it not x+7=19?
x= age now+ the 7 years equals final age:19
not saying ur wrong just questioning
Apologies for the confusion. You are correct. The equation should be: x + 7 = 19.
r u sure?
I apologize for the mistake in my previous response. You are right, the correct equation is x + 7 = 19. Thank you for pointing that out.

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?
To determine the number of hours 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 would be:
h = 5 1/2 - 3 3/4
