Answer:a) W=-17x/-5

Step-by-step explanation:

Number of books = x

6W-(X×17)=W

6W -17X = W

Collect like terms

-17X= W-6W

-17X = -5W

Divide both sides by the coefficient of W

-17X÷ -5 = -5W÷ -5

W = -17X÷ -5

B) W = 34

W = -17X ÷ -5

34 = -17X ÷ -5

Cross multiply

-17X = 34× -5

-17X = -170

Divide both sides by the coefficient of X

X = -170 ÷ -17

X = 10

∴ Angela bought 10 books

PIT_PIT [208]
The probability of having a 17 is the number of ways of having 17 divided by the number of different possible outcomes.

Ways of having 17:

Die 1     Die 2     Die 3    sum
6            6            5          6+6+5 = 17
6            5            6          6+5+6 = 17
5            6            6          5+6+6 = 17

Those are the only 3 possibilities of having 17 (you can only loose 1 point).

The total number of outcomes are 6*6*6 = 216

So the chances (probability) to win is 3 / 216 = 1/72 = 0.0139
