suppose you are in your last semester of college and have a 2.75 GPA after 105 credit hours if you are taking 15 credit hours in
Valentin [98]

Answer:

The overall CGPA would be 2.90 so it is not possible for hum to secure a CGPA of 3 for graduation.

Step-by-step explanation:

Given,

CGPA = 2.75

Credit hours = 105

Last semester GPA = 4

Last semester credit hours = 15

CGPA = \frac{sum of (Credit hours of each subject * GPA of each subject)}{Total credit hours}credit hours * gpa

in our case, it would be:

CGPA = \frac{(2.75*105)+(4*15}{105+15}

=> \frac{(288.75)+(60)}{120}

=> \frac{348.75}{120}

=> 2.90

The overall CGPA would be 2.90 so it is not possible for hum to secure a CGPA of 3 for graduation.

Solve the system of equations and choose the correct ordered pair. 
Ksivusya [100]
L.H.S is already equal, so just subtract 1st equation from second, 
2y = 12
y = 6

Now, substitute it in 1st equation, 
2(6) = 4x + 8
4x = 12 - 8
x = 4/4
x = 1

In short, Your Answer would be Option C) (1, 6)

Hope this helps!
