Z=7f/r+4 , solve for r

              7f

     r =  -  4

                z

Step-by-step explanation:

I will assume that you meant:

         7f

z =

        r + 4

Solve for r.  Start by interchanging z and (r + 4):

               7f

r + 4 =

                z

Now subtract 4 from both sides.  This isolates r:

              7f

     r = - 4

                z

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
