On the exam, the average score is 300 and 10 is the standard deviation. What is the score of someone in the 50th percentile? (No links please! will give brainliest just for the answer!)

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10

Two triangles can be formed with the given information. use the law of sines to solve the triangles. b = 49°, a = 16, b = 14
