Step-by-step explanation:

y = 2/5 x - 9/5

when x = -1,

the value of y = 2/5(-1) - 9/5

= -2/5 - 9/5 = -11/5

when x = 0

=> y = 2/5(0) -9/5

= 0-9/5 = -9/5

when x=1

=> y = 2/5(1) - 9/5

= 2/5 - 9/5 = 7/5

Three teams, A, B and C, play in a competition.

Snezhnost [94]

Answer:

42 games

Step-by-step explanation:

From the ratio, we can deduce that;

For every 3 games A won, B won 1

Thus, if B won 10, then A has won 3(10) = 30

From the second part;

For every 1 game won by C, B won 5

since B won 10, then C won 10/5 = 2

So the total number of games won is;

A + B + C

= 2 + 30 + 10 = 42 games
