4x+1-5x=5-(x+4)
Do the parenthesis first which’s
4x+1-5x=-5x-20
Now we have to combine the like terms
Which’s -x+1=-5x-20
Now we have to put the x together
-x+1=-5x-20
-x. -x
1=4x-20
Also we need to put the x by itself so we will add 20 to both sides
1=4x-20
+20 +20
Which is 21=4x
Now we have to divide the both sides by 4 to get the x by itself
21/4=4x/4
So the answer will be 21/4=x
Answer:
7/12 of an hour or 35 minutes
Step-by-step explanation:
For Urn 1,
total number of balls = 8 (green balls) + 12 (red balls) = 20 balls
The probability of picking a red ball from Urn 1 is equal to 12/20 or 6/10 or 3/5.
For Urn 2,
total number of balls = 5 (green balls) + 8 (red balls) = 13 balls
The probability of picking a red ball is 8/13.
The probability of picking both red balls from the two urns is the product of the two probabilities which gives us the answer which is equal to 24/65. The answer is letter B.
