Answer:
15.78 %
Step-by-step explanation:
It is given that,
Miguel made 80 on his Math test. He made 95 in last week's Math test.
We need to find the percent change on his scores. It can be calculated as follows :
So, there is a percent change of 15.78%.
The point (6, 6) is the mid-point of A and B. Then the coordinate of the point B is (7, 5).
<h3>What is coordinate geometry?</h3>Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
Point A (5, 7) is reflected over the point (6, 6) and its image is point B. Then the point (6, 6) is the mid-point of the A and B. Then the coordinate of the point B will be

Answer:
Gabrielle is 69 while Mikhail is 23.
Step-by-step explanation:
Let G represent Gabrielle's age and M represent Mikhail's age.
Gabrielle is three times Mikhail's age. In other words:
The sum of their ages is 92. In other words:
This is a system of equations. Solve. Substitute in G:
Thus, Mikhail is 23. Now, find Gabrielle's age:
Gabrielle is 69.
