Lady bird [3.3K]3 years ago
4 0

Answer:

D

Step-by-step explanation:

2x + 3y = 18

3x - 3y = 12

the 3y and -3y cancel and you add the other like terms

5x = 30

x = 6

plug x back into any of the equations

2(6) + 3y = 18

12 + 3y = 18

3y = 6

y = 2

answer is (6,2)

Lady bird [3.3K]

Answer:

0.5220

Step-by-step explanation:

The probability that they are all contaminated will be 0.85 * 0.85 0.85 * 0.85 = 0.52200625

This is 0.5220 to four decimal
