Find how much he will earn
we know he will earn 8 hours sofirst find how many he earns
9 per hour
8 hou
9*8=72
72+6*numberofdeliveries=155
minus 72
6*numberofdeliviers=83
divide by 6
number of delevieries=13.8
he can't make 13.8, round up to get 14
answer is 14 deliveries
You can make a table like this:
If 1 bag=5 pounds
Then 6 bags must equal six times the weight of the first bag
5 times 6=30
Your answer is reasonable because 5+5+5+5+5+5=30
a.k.a
=5 =30
Answer:
I am not sure how your teacher wanted you to estimate the answer but I solved it for you. Hopefully this helps.
Step-by-step explanation:
7x-y=7
x+2y=6
14x-2y=14
x+2y=6
add both equations
15x=20
x=20/15
x=4/3
x+2y=6
4/3+2y=6
2y=6-4/3
2y=18/3 -4/3
2y=14/3
divide both sides by 2
y= 14/3 divided by 2
y=14/3(1/2)
y=14/6
2y=
Answer: 1760
Step-by-step explanation:
Cost of 1 flyer = $0.25 or 25 cents
Budget is = $555
Let us assume that supplies cost is a one time cost
Cost of supplies for one time = $115
So budget remains =
So in $0.25 we get = 1 flyer
In $440 we get = = 1760
Hence, we can buy 1760 flyers.

Answer:
The probability is 
≅ 
Step-by-step explanation:
Let's analyze the question.
There are 15 students in the 8th grade.
The students are randomly placed into three different algebra classes of 5 students each.
We are looking for the probability that Trevor, Terry and Evan will be in the same algebra class.
One possible way to solve this question is to think about the product probability rule.
We can use it because we are in an equiprobable space. (And also the events are independent).
Let's set for example a class for Evan.
The probability that Evan will be in a class is 
Then for Terry there are 
places out of 
that puts Terry in the Evan's class.
We write 
Finally for Trevor there are 
places out of the remaining 
that puts Trevor in the same class with Evan and Terry.
Using the product rule we write :
The probability of the event is ≅
