Is the given number a solution of the equation? c=2c-4; 8
a yes
b no

A. yes

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

To figure out if the number given is the solution to the equation we must solve the equation. We do this by substituting the variable (C) in the equation with the number that was given. Now let's solve this,

..... add 4 on both sides

.... divide both sides by 2

We can see that if the value of the variable c becomes 6, then 8 becomes a possible value. Therefore the answer is A. yes

I hope this answered your question. If you have any more questions feel free to ask away at .

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
