Answer:

For blue its 3/12 = 1/4 = 25%

For red it's 6/12= 1/2= 50%

For green 2/12= 1/6= 17%

For black 1/12= 8%

Step-by-step explanation:

All you have to do is add up all the marbles 3 + 6 + 2 + 1 = 12 and then you put the number of marbles for each color and divide it by 12 which gives you those percentages. I don't know if you wanted the answers in percentages or fractions so I gave you both . Good luck!!

Chang made $156 for 13 hours of work at the same rate, how many hours would he have to work to make $108?
sdas [7]

Answer:

  9 hours

Step-by-step explanation:

"At the same rate" means time and wages are proportional.

  time/wages = t/$108 = (13 h)/$156

  t = 108(13 h)/156 . . . . . . . . . . . . . . . units of dollars cancel

  t = 9 h

Chang would have to work 9 hours to make $108.

13+x+195=13(x+15)...
LUCKY_DIMON [66]
First, let's expand the right side.  Now our equation is

13+x+195=13x+195

Now, we gather all the terms with x in it on the left side, and the numbers without x on the right.  We get:

-12x=-13

And then we can make this

12x=13

We divide both sides by 12 to get x on its own, so x = 13/12 or 1.08
