Answer:

<em>4/9 [Less likely]</em>

Step-by-step explanation:

2 purple

5 pink

2 blue

The total is 9.

5/9 is pink out of total (basically, the whole bag of marbles).

This is if you were picking pink.

Now, we subtract.

9 - 5 = 4 --> 4/9

The reason we do this is because we are finding the probability of not picking pink.

The end result is 4/9 because there is still 4 other marbles (other than pink) out of all 9 that we could pick.

X = 16 - 4y<br> 3x + 4y =8 <br> substitution method
8_murik_8 [283]

Answer:

i think x = -4, y = 5

Step-by-step explanation:

x = 16 - 4y

3x + 4y = 8

3(16 - 4y)+4y = 8

48-12y+4y = 8

48-8y = 8

48-8 = 8y

40 = 8y

5 = y

so

x = 16 - 4y

x = 16 - 4(5)

x = 16 - 20

x = -4
