There are 15 pencils altogether. Of these, 4 are green. Thus, P(green) = 4/15.
3+6
There are 3 red and 6 blue pencils. Thus, P(red or blue) = --------- = 3/5
15
First you multiply 6(x) then you multiple 6(8)
Your equation should now look like this: 6x-48=72
Subtract 48 from both sides
Your equation should now look like 6x=120
Divide by 6
Answer is 20
100/5= 20
20 x 4 = 80
80 + 43 = 123
if my math is correct then none are correct
