Answer:
126
Step-by-step explanation:
21 + 4 = 25 (blue plus white marbles)
150/25 = 6 (all the marbles divided by how many we know are white and blue)
21 x 6 = 126
The answer is: b) a = 63°
B) y=x-4 not sure how to explain it, but because the y intercept is -4, it is almost certain that the last number will ne -4 and since x is equal to 4 y must equal x-4. Might be wrong though ('o')
