2. David has 5 times as much as money as Michael at first. Both received $87 each. David has twice as much as money as Michael now. How much did David have at first?​

Michael had $29

   David had $145

Step-by-step explanation:

          D = 5M

  D + 87 = 2(M + 87)

5M + 87 = 2M + 174

       3M = 87

         M = 29

D = 5(29) = 145

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
