Hey, I'm not sure if I'm wrong or not but wouldn't the answer be c divided by pi? or c/pi

You are correct

It is C divided by PI

Step-by-step explanation:

c=pi x D

Using substitution method replace letters with numbers

12(c)=3(pi) x 4(d)

we want 4(d) the subject of the formula

4(d)=

12/3 =4

so it is 4(d)=12(c)/3(pi)

so D=C/PI

yeah and

step-by-step explanation:

you know what it isnt great cheating

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
