Answer:
A) Bobby's overall grade is 70.4%
Step-by-step explanation:
To solve this problem we must calculate the percentages each grade represents from the overall grade. Therefore:
assignment = 85*30% = 85*30/100 = 25.5%
tests = 72*20% = 72*20/100 = 14.4%
exam = 61*50% = 61*50/100 = 30.5%
total = assignment + tests + exam
total = 25.5 + 14.4 + 30.5 = 70.4
Bobby's overall grade is 70.4%. Therefore the correct answer is A).

<h2>d) X= - 16/9</h2>
Step-by-step explanation:
2x - 4 - 6(x + 1) = 5x + 6
2x - 4 - 6x - 6 = 5x + 6
2x - 6x - 5x = 4 + 6 + 6
-9x =16
x= -16/9
