Answer:
4
Step-by-step explanation:
Let's say B is the number of boys and T is the number of teachers.
T / (B + 18) = 2/21
B/18 = 4/3
Solve the second equation for B.
B = 24
Plug into the first equation to find T.
T / (24 + 18) = 2/21
T = 4
Answer:
transitive property
Step-by-step explanation:
According to transitive property, if there is some relation between a and b by some rule , and then there same relation between b and c by some rule, then
A and C are related to each other by some rule.
Example:
A = B
B=C
then by transitive property
A=C
As value of A and C are same that is B we can say that A is equal to C whose value is B.
_______________________________________________
Given
a =2z and 2z=b
here both c and b has value equal to Z , Thus, they follow transitive property.
we'd do the same as before on this one as well.
if we take 27.99 to be the 100%, what is 12 off of it in percentage?
Because f(x)=x, goes through origin. So x and y -intercept are one point (0,0).
