Answer:

The answer is k = 28

Step-by-step explanation:

\frac{12}{k}=\frac{18}{42}

Cross multiply. Remember, \frac{a}{b}=\frac{c}{d} ⇒ ad=bc

\frac{12}{k}=\frac{18}{42} ⇒ k·18=12·42

k·18=12·42

Simplify

18k=504

÷18 on both sides

k=504÷18

Simplify

k=28

katrin2010 [14]

The score of Raven is 9 points

<em><u>Solution:</u></em>

Let the point scored by bangal be"x"

Score of Raven = 40 points

Given that,

The ravens scored 13 more than three times number points that the bangals scored in their last game

Score of raven = 13 + 3(score of bangal)

40 = 13 + 3x

Solve the above equation for x

3x = 40 - 13

3x = 27

x = 9

Thus the score of Raven is 9 points
