Think of ratios as fractions.
5:8 is the same as 5/8
6:7 is the same as 6/7
Divide each fraction
5/8 = 0.625
6/7 = 0.857
-------------------------------------------------------------------------------------------------------------------
0.857 > 0.625 ∴ 6:7 is greater, and is your answer

Okay, here we have this:
Considering the provided information and grades, we are going to calculate the requested GPA, so we obtain the following:
Then we will substitute in the following formula:

Then:

Finally we obtain that the student's GPA for that term is approximately 3.06.
Answer:

Step-by-step explanation:
Let us write the equations in standard form:

We have
and
Since the eccentricity of this conic is less than 1, the conic represents an ellipse.
The second equation is
.
This is a hyperbola, because eccentricity is more than 1.
The third equation is
.
This is a parabola, because eccentricity is 1.
The fourth equation is
.
This is also a hyperbola, because eccentricity is more than 1.
This is an easy one!
x+4 = 8
x = 8-4
Therefore x = 4.
