54 teachers
Step-by-step explanation:
Students ratio :17+18=35 then 630/35= 18 18x3t=54
Thirteen dollars and twenty two cents just add 15% to $11.50.
P=2L+2W
80=2*26+2W
so then you could find the missing number of W which is
W=14
Answer: 
Step-by-step explanation:
To find the least common multiply, you must descompose 12 and 15 into their prime factors, as you can see below:
12=2*2*3=2²*3
15=3*5
Choose the common and non common numbers with their greastest exponents:
3*5*2²=60
Now you must choose the common and non common variables with their greastest exponents:
n³
Therefore, you can conclude that the least common multiply is:
