Answer:
x= 50
Step-by-step explanation:
Add up the other two numbers, 15 and 25, which will get you 40. subtract 40 from 90 and you have 50.
It will be 13 min because you have to work backwards. The area of a square is the sides squared. Just do the square root of 169 and you get 13.
I'm going to show you two ways to do it.
Way #1 is the slogging way.
Way #2 is the clever way.
Way #1:
' One hundred percent ' means ALL of something.
ALL of the students in the school is the same as 100% of them.
If 10% are absent, then 90% are present.
90% means 0.9 .
1620 students = 90% of the school.
1620 = 0.9 x school total
Divide each side by 0.9: 1620/0.9 = total school
1800 = total school
How many were absent ?
10% of them.
10% means 0.10 .
0.10 x 1800 = 180 students absent .

Way #2:
' One hundred percent ' means ALL of something.
ALL of the students in the school is the same as 100% of them.
==> If 10% are absent, then 90% are present.
==> The number of students present is 9 times the number who are absent.
1620 = 9 x the number absent
Divide each side by 9 : 1620 / 9 = the number absent
1620 / 9 = 180 absent .
