Answer:
n<-27
Step-by-step explanation:
you have to get n by itself, to do this divide -3 from both sides of the equations.
-3n/-3<81/-3
n<-27
the answer is n<-27
One way is to estimate
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
the number 61 is between 49 and 64 therefor the square root of 61is between the intigers 7 and 8 or -7 and -8
Therefore, there are
millimeters in seven meters.
