There are two solutions to this question, one is positive and the other is negative:
She must at least score a 38
To get the average you need to add 45 + 32 + 37 together than divide it by the amount of numbers added, in this case 3.
45 + 32 + 37 = 114
114÷3 = 38
Answer: A. 289.5
Method: 48.25 x 6 = 289.5
Answer: 
Step-by-step explanation:
For this exercise you must remember that the original figure (before a transformation) is called "Pre-Image" and the one obtained after the transformation is called "Image".
A Translation is defined as a transformation in which the figure is moved a fixed distance in a fixed direction. In this kind of transformatiosn the size and shape do not change and the figure is not flipped.
In this case you know that the Pre-Image is the Triangle FGH.
You can identify in the picture that its vertex H has these coordinates:

Where:

Since the rule is:
→ 
You can substitute the coordinates of H into the given rule in order to find the coordinates of H'. This is:
