Answer:
86
Step-by-step explanation:
In this question, we are asked to calculate the average mean score for a group of students split into two different emerging groups.
We calculate the total score for each of the groups. This is done by multiplying the average score by the number of students.
Total score of section A is 15 * 80 = 1,200
For section B, total score is 20 * 90 = 1,800
Overall score is thus 1200 + 1800 = 3000
We add the scores together and divide by the total number of students in both sections
Average score is thus 3000/35 = 85.71 which is approximately 86
Answer:
multiply 4 and 8 to get 32
Step-by-step explanation:
After substituting, the expression is ...
4·8 +9/7
The order of operations tells you to do multiplication and division before addition and subtraction. You do them left-to-right. The multiplication on the left is 4·8, so you do that first. The result is ...
32 + 9/7
Now, you can do the division:
32 + (1 2/7)
And, finally, the addition:
33 2/7
___
Or, you could skip the division and go straight to adding a whole number and a fraction:
(32·7 +9)/7 = (224+9)/7 = 233/7
