The recyclables have been sorted into plastic and glass. The number of plastic items is 30 less than nine times the number of gl
Colt1911 [192]

Answer:

  B,  9

Step-by-step explanation:

Let g represent the number of glass items. Then the number of plastic items is (9g -30). If 85% of items are plastic, then 100%-85% = 15% of items are glass. The ratio of plastic to glass is ...

  85%/15% = (9g -30)/g

  17/3 = 9 -30/g . . . . simplify

  30/g = 9 -17/3 = 10/3 . . . . . . add 30/g -17/3

  g = 30(3/10) = 9 . . . . . . . . . . multiply by 3g/10

There are 9 glass items.

_____

<em>Additional comment</em>

The number of plastic items is 9(9) -30 = 51, and the total number of items is 51+9 = 60. The percentage of plastic items is 51/60 = 85%.

__

There are many other ways the equation(s) could be written, including using a system of two equations. For example ...

  • p = 9g -30
  • p/(p+g) = 0.85 . . . . . plastic is 85% of the total

Answer:

60 degrees

Step-by-step explanation:

On the diagram, we can see that the two angles have a dash on each of them. This means that they have the same measure.

So, if angle ABD is 60 degrees, then angle DBC would also be 60 degrees.

I hope this helps!
