A second number is 6 less than a first number. A third number is twice the first number. If the sum of three number is 306, find

Serga [27]

Answer:

first number = 78

second number = 72

third number = 156

Step-by-step explanation:

first number = a

second number = b

third number = c

we have

b=a-6 equation 1

c=2a equation 2

a+b+c=306 equation 3

using equation 1 and equation 2 in equation 3 we have

a+a-6+2a=306

4a=306+6

4a=312

a=312/4

a=78= first number

b=78-6=72=second number

c=2*(78)=156 third number

Assume that f is a one-to-one function.

Pavlova-9 [17]

It is given in the question that f is a one-to-one function.

And for a one-to - one function,

$f(a)=b, \ then \ f^{-1} (b) =a$

So we will get

$a. If \ f(3)=15, \ then \ f^{-1} (15) =3
\\
b. If \ f^{-1}(6)=4, \ then \ f(4)=6$
