Answer:
x=4.8
Step-by-step explanation:
5x:9 = 8:3
It can also be written as
5x/9 = 8/3
Cross multiply
5x*3 = 8*9
15x = 72
Divide both sides by 15
15x/15 = 72/15
x =4.8

Step-by-step explanation:
just add 12+7 also no idea what the other one is sorry!
First pear Second pear probability
green (3/7)---------green (2/6) (3/7)*(2/6) = 1/7
---------red (4/6) (3/7) *(4/6) = 2/7
red (4/7)-------------green (3/6) (4/7)*(3/6) = 2/7
-------------red (3/6) (4/7)*(3/6) = 2/7
-------------------------
1/7 + 2/7 + 2/7 + 2/7 = 1
The probailities that two are green are: 1/7
The probabilities that one is green and the other is red are:2 /7 + 2/7 = 4/7
The probabilities that two are red are: 2/7
