Answer:

The answer to your question is: 3.7 hours

Step-by-step explanation:

Kam can make 72 cookies/ 3 hours

Madison can make 120 cookies/4 hours

Time to make 200 cookies together = ?

First, calculate the number of cookies make per hour

Kam            72 ---------------- 3

                   x   ----------------  1 hour

  x = 72/3 = 24 cookies/h

Madison

             120 -------------   4 hours

               x ---------------      1 hour

x = 120 / 4 = 30 cookies

Now we write and equation where "t" will be time

         24t + 30t = 200      and solve it

         54t = 200

        t = 200/54

        t = 3.7 hours

scZoUnD [109]

Answer:

x = 5

Step-by-step explanation:

ABC is an isosceles triangle

So

<A = <C = 73

<B = 180 - 2 * 73

<B = 180 - 146

<B =  34

Given <B = 6x +4

So

6x + 4 = 34

6x = 30
