1.
The temperature in morning is below zero, so you have to count up to zero and then past to get the noon temperature:

-6 -5 -4 -3 -2 -1 0 1 2 3 4

Since the temperature increased by 10 degrees, then the temperature at noon would be 4 degrees. An easy way of looking at it is: -6 + 10 = 4

2.
Add all three temperatures, and divide by the number of temperatures (three):

(-6 + -14 + 8)/3 = -12/3 = -4

The average temperature over those three mornings was -4 degrees.

1) The morning temp was -6 degrees at noon the temp had increased by ten degrees

Add-6 and 10

Noon temp 4 degrees

2)Add the three temps first

-6+(-14)+8

-20+8=-12

Divide -12 with 3

-12/3=-4

Anwsar= -4

1) -6 + 10 = 4 Answer: 4 degrees in noon

2) -6 + (-14) +8 = -12
To find the average: (-12)/ # of mornings = (-12)/3 = -4
Answer is -4 degrees

1) -6+10=4 so the answer is 4 degrees

2) (-6+(-14)+8)/3=-4 so the average war -4 degrees

1. -6 + 10 = 4 degrees

2. (-6 + (-14) + 8) / 3 = -4 degrees

Hey. I'll give you the answers to these in a second. If you've posted these because you don't know how to answer them, then I think you could really do with telling your maths teacher that you struggle with maths, and could do with a bit of extra help. Your teacher won't mind, and don't worry about what your mates are likely to say about asking for extra help - when it comes down to it, this is stuff you'll really need to know about in life. Your teachers are there to help you with this stuff.

Anyway, I promised some answers.

First some background. Numbers are like a line. All numbers are like places on this long line. Like this:

-10 -8 -6 -4 -2 0 2 4 6 8 10
----------------------------------------------------------------
<------smaller bigger ------------>

and so on. Adding numbers moves up the line, and subtracting moves down it.
Negative numbers (or 'minus' numbers), which I presume are the thing making this question tricky for you, are just places on this line to the left of the one called zero.

If you start at -6, and go up 10, you end up at 4.

The second question you've written here is asking you to find the average of three different numbers, two of which are minus numbers.

When you want to find the average of a group of values, you start by adding them all together, and dividing your answer by the number of values you started with. Negative numbers are no different to other numbers when it comes to adding them together, except when you add a negative number, you're still making the total smaller. Adding a negative number is the same as subtracting.
for example : 3 + -5 is -2.

Draw yourself a line like the one above, but one that goes much further. Move your finger down the line, going left when it's adding a minus number, and right when you're adding a positive number. The number you finish on is your final answer.

Good luck. If you've got any more questions, print this out and show it to your teacher, and ask them to clarify anything. They'll be glad you actually care enough to ask.

num 1 -6+10 =-4

-6+-6+-6+-14+8 divide by 5

2007-08-30 16:28:05 · answer #7 · answered by J 2 · 0 0

1) 4 degrees
2) -6+-14+8=-12 -12/3=-4 minus 4 is the answer

I used a calculator ;-)

1. To find out the answer of number 1... U gotta add a positive number to a negative number

2. To find out the average temperature u have to add 0.6+0.14+8 and devide the sum by 3 and you have the average temp
