We set up the equation (70+64+83+x)/4=75
Multiply by 4 on both sides: 70+64+83+x=300
Combine like terms on left side: 217+x=300
Subtract 217 from both sides: x=83
So Sara must get at least an 83% in order to maintain a final average of 75%
Hope this helped!

Answer:
No
Step-by-step explanation:
If you’re wanting the yes or no answer, keep reading.
If you’re wanting a number for y and x, we can’t give that to you. It’s infinite!
Since both y and x = 0, the equation would be set up as 0 = 0-3. You can see the equation is false, so it would be a no.
Answer: Option C. Ellipse
Step-by-step explanation:
The general equation of an ellipse has the following form:
Where the point (h, k) is the center of the ellipse
In this case we have the equation
Note that its shape matches that of a ellipse with center (9, -2)
Therefore the answer is the obtion C
