X+y+z=51
y=2z
z=9+x
subsitute those
x+2z+9+x=51
x+2(9+x)+9+x=51
x+18+2x+9+x=51
4x+27=51
minus 27 both sides
4x=24
divide by 4
x=6
sub back
z=9+x
z=9+6
z=15
y=2z
y=2(15)
y=30
the numbers are
6,30,15
It’s an intriguing question with no reliable answer
Answer:
A=40
B=.625
Step-by-step explanation:
1.25/.25 is 5
1/.25 is 4
.5/.25 is 2
5 x 4 x 2 is 40
multiply all of the sides together
or
multiply the boxes sides together then x 40
Answer:

Step-by-step explanation:
Given:
The equations given are:

Now, a linear function is of the form:

Where, 'm' and 'b' are real numbers and 
Equation 1: 
Simplifying using distributive property, we get:

The above equation is of the form
. So, it represents a linear function.
Equation 2: 
Here, both sides of the equation has same variable 'X'. So, it will form an equation of 1 variable. So, it's not a linear function.
Equation 3: 
Simplifying the above equation. This gives,

This is not of the form of the linear function. So, it is also not a linear function.
Equation 4: 
Simplifying the above equation. This gives,

This is not of the form of the linear function. So, it is also not a linear function.
