Answer:

one of the red things

Step-by-step explanation:

if you subtract two red things from each side, you are left with two red things on one side and two E-tanks on the other. Then you can square root each side to find that one red thing equals one E-tank. Sence we don’t know the value of the red thing, this is as far as we can go

the points (-4, -2) lies on a circle. what is the length of the radius of this circle if the center is located at (-8. -10) ?

You would subtract the x coordinates of each so -8 - -4 which equals -4. But since length cant be negative it would just be 4.

3xc = -5, solve for x

atroni [7]

Answer:

$x = -\dfrac{5}{3c}$

Step-by-step explanation:

You want x alone on the left side.

x is being multiplied by 3 and by c.

The opposite operation of multiplication is division. You must divide 3xc by 3c to end up with just x.

You must do the same operation to both sides of an equation, so divide both sides by 3c.

$3xc = -5$

Divide both sides by 3c.

$\dfrac{3xc}{3c} = \dfrac{-5}{3c}$

Simplify both sides.

$x = -\dfrac{5}{3c}$

What is the justification for the step taken from line 2 to line 3?

natima [27]

Answer:

They subtracted 2x from both sides.

Step-by-step explanation:

They removed 2x from each side because in order to find x it will have to be removed on one side. Since 2x - 2x = 0 it is 2x is out of the equation for the right side and on the left side -2x -(-4x) = -6x which means that there is one x variable left in the equation thus making it solvable.
