Cp=7512.75×[100÷(100+77÷4)]
=7512.75×(100÷119.25)
=6300
c.p=6300
So just your normal equation.
We need to isolate x alone.
First lets write out our equation
3 +7x = 12
Lets do this step by step.
first subtract 3 from both sides.
3 + 7x = 12
-3 = -3 it cancels out on the left side and we solve on the right side.
*************
7x = 9
second we divide both sides by 7
7x = 9
÷7 = 7 we got the x alone and we just write 9/7 as our answer.
x = 9/7
Or as a decimal.
9/7 could be <span>1.28571428571429
</span>
Either will work.
x = 9/7
or
x = <span>1.28571428571429

Have a nice day. :)

So for perimeter you need to find out the total of all the sides. To find out side AB, you make a triangle and find out the hypotenuse.
a=5 and b=6
a square= 25 b square= 36
25+36= 61
Square root of 61 is 7.81
So side AB is 7.81 ft
Now we need to find out side BC.
a=3 and b=4
a square is 9 and b square is 16.
9+16 is 25
Square root of 25 is 5
Side BC is 5 ft.
Because it's a rectangle, side CD will be 7.81 and side DA will be 5.
7.81*2+5*2= 25.62 ft
So the perimeter of the rectangle is 25.62 ft or C.
