one bag contains x pencils
5 bags contain 5x pencils
after adding 3 pencils to each bag
total no of pencils = 5(x+3)
According to question,
5(x+3)=45
x+3=45/5
x+3=9
x=6
one bag contained 6 pencils before adding
Answer:
The hourly charge is $4 per hour for the first 3 hours.
The rate then drops to $2 per hour until the end of the 6th hour.
The hourly rate drops further to $1 per hour between the 6th and 10th hours.
The maximum price of the bike rental is $30.
Step-by-step explanation:
The slope of the graph corresponds to the hourly rate for the bike rental.
During the first three hours of the bike rental, the price increases by $4 each hour.
Between the 3rd and 6
th hours, the slope of the graph is 2, which means the hourly rate of the bike rental is $2 per hour.
Between the 6th and 10th hours, the rate is $1 per hour.
After the 10th hour, the price, P, stops increasing. The maximum price of the bike rental is $30.
so it'd be the first, third and fourth one. all you gotta do is draw a vertical line through the middle of the 1st, 3rd and 4th.
The probability of matching the first one correctly is 1/3 .
Then there are only two baby-pix left, so ...
The probability of matching the second one correctly is 1/2 .
Then there's only one baby-pic left, so ...
The probability of matching the third one correctly is 1 .
So the probability of matching all three correctly is
(1/3) x (1/2) x (1) = 1/6 = (16 and 2/3) percent .
Answer:
-5(p+3/5)=-4 what is the answer
The answer is P = 1/5
Step-by-step explanation:
from the question -5(p+3/5)=-4 applying the law of BODMAS we will use -5 to open the bracket
we have [-5(p) + -5×3/5] = -4
-5p - 3 =-4
collecting the like terms
we have; -5p = -4 + 3
-5p = -1
divide both sides by -5
we have; -5p/-5 = -1/-5
the minus sign cancels out and we have
p= 1/5
check your answer by sloting the value of p into the question -5(p+3/5)=-4
-5(1/5 + 3/5) = -4
-4=-4
