Solve 4x- c= k for x.
ira [324]

Answer:

Step-by-step explanation:

Let's begin the solution by isolating the 4x term:

4x- c= k  =>  4x = c + k

Now divide both sides by 4:

          c + k

x = --------------

              4

This does not match Answer C, but would match Answer C if k + c were divided by 4.  Answer C, as shown, is incorrect.

I have 120 cm of framing material to make a picture frame, which will be most pleasing to the eye if its height is 2/3 of its wi
Ilia_Sergeevich [38]

 

The formula for perimeter is:

<span>P = 2 h +  2 w</span>

where P is perimeter = 120 cm, h is height, w is width

we are also given that: h = (2/3) w, therefore:

P = 2 (2/3) w + 2 w = 120

(4/3) w + 2 w = 120

w = 36 cm

 

Therefore l is:

l = (2/3) w = 24 cm

 

<span>Hence the dimension should be 24cm by 36 cm</span>
