the bag contained only red marbles and white marbles. If the ratio of red marbles was 7 to 5,what fraction of the marbles were white?

5/12

Step-by-step explanation:

Given that:

Ratio of Red to white marbles = 7 to 5

Total = (7 + 5) = 12

Number of red marbles = 7

Number of white marbles = 5

Hence, fraction of white marbles = (number of white marbles / total number of marbles)

Fraction of white marbles = 5/12

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
