Can someone please help me on this question? Use the following diagram to find the fraction representing each collection of dots
ale4655 [162]

Answer:

  a.  4/7

  e.  3/4

Step-by-step explanation:

For each part of the question, count the dots that meet the first requirement, and count the dots that meet the "fraction of ..." requirement. The desired fraction is the ratio of these numbers. In the answers above, we have reduced the fractions to lowest terms, but the question does not seem to require that.

__

a. The desired fraction is ...

  (dots in the triangle)/(all dots) = 16/28 = 4/7

__

e. (dots in the rectangle not in the circle)/(dots in the rectangle) = 9/12 = 3/4

If 14y - 4 = 24y + 26 , then 12y =
harkovskaia [24]
Solutions 

To solve the equation we have to isolate 12y

14y - 4 = 24y + 26

-4 - 26 = 24y - 14y

-30 = 10y

10y = -30

y =- -30/10

y = -3

12y =12/-3

12y = -36

Therefore, 12y = -36
