There are 90 students in grade 5, and 10% of them were absent today. in grade 6, 15% of the 80 students were absent today. what was the total number of students in the two grades who were present today?

21 students

Step-by-step explanation:

90 x .10 = 9

80 x .15 = 12

9 + 12 = 21 students

it has the same slope and a different y-intercept

hope this : )

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
