(3y - 8)             y
----------    =  ----------
  12                  5

cross multiply

5(3y - 8) = 12y.....distribute thru the parenthesis
15y - 40 = 12y ....subtract 15y from both sides
-40 = 12y - 15y....simplify
-40 = -3y ....divide both sides by -3
-40/-3 = y
13 1/3 (or 13.333) = y

Divya spends all of her free time playing with her building blocks. She owns building block sets with 333 pieces, 555 pieces, an
DiKsa [7]

Answer:

  5 sets

Step-by-step explanation:

The average number of pieces per set is the ratio of the total number of pieces to the total number of sets.

Let x represent the number of 3-piece sets. Then the total number of pieces is ...

  3x +5(5) +10(2) = 3x +45

The total number of sets is ...

  x +5 +2 = x +7

We want the ratio of these numbers to be 5 pieces per set:

  (3x +45)/(x +7) = 5

  3x +45 = 5x +35 . . . . . multiply by (x+7)

  10 = 2x . . . . . . . . . . subtract (3x+35)

  5 = x . . . . . . . . . divide by 2

Divya owns 5 sets with 3 pieces.

_____

<em>Alternate solution</em>

Each 10-piece set has 5 more pieces than average, so the two of them total 10 more pieces than average.

Each 3-piece set has 2 fewer pieces than average. The total number of 3-piece sets must have a total of 10 fewer pieces than average in order to balance the excess of the 10-piece sets. That is, there must be 10/2 = 5 of the 3-piece sets to have a total lof 10 fewer pieces than average.

Altogether, the differences from average must total zero.

Savings should be treated as another type of
Taya2010 [7]

Answer:

B,  Net income

Step-by-step explanation:

Savings cannot be treated as deduction as deductions are compulsory done by the employer for loans, taxes, and other liabilities as PF etc.  But savings is voluntarily done by the income holder after setting aside amount for all other expenditure necessary to sustain living.

Savings cannot be treated as short term goal, as sometimes savings are for long term as children's education, marriage, old age pension, etc.

Savings cannot be treated as expenditure as expenditures are getting some goods or services by paying some money.  But savings is not giving money to get service or good but to hold it for future use

THus the appropriate answer is savings is net income i.e. income over all expenditures.
