Question

Gerald can complete a math assignment in 2 hours and a physics assignment in 1 hour. If he has 8 hours to complete a set of assignments, how many math assignments can he complete if he decides to leave the science assignments for the next day? This situation is given by 2x + y = 8, where x is the number of completed math assignments and y is the number of completed science assignments. (x 0, y 0, x and y take only integer values). . A) 1. B) 2. C) 3. D)4. E) 5 .

Answer 1

 

The solution would be like this for this specific problem:

Since he’d leave the science assignments for the next day, you just need to remove the y in the equation because y represents the number of science assignments. The equation 2x + y = 8 will be converted to 2x = 8.

2(4) = 8

If he has 8 hours to complete a set of assignments, then he can complete 4 math assignments if he decides to leave the science assignments for the next day.

The correct answer between all the choices given is the last choice or letter D. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.
