4 0

The coefficient of y is 14 and the constant is 13.

You can find this by combining like terms first.

6x + 12y + 5 + 2y + 8

6x + 14y + 5 + 8

6x + 14y + 13

Now the coefficient is the number next to y. The constant is the number on its own.

Z=7f/r+4 , solve for r
lora16 [44]

Answer:

              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

Juli2301 [7.4K]

There are two ways to do this:

Way 1- Since you know there are 4 people and each will pay 25%, you know that every person will pay equally / the same amount so you can just do 115/4 and get $28.75 per person

Way 2- You can convert 25% into a decimal by multiplying it by 100 and getting 0.25 and multiplying 0.25 x 115 to get 25% of 115, which is what everyone will pay and you get B $28.75
