Add up all of the numbers and then divide by the amount of numbers you have, basically the sum divided by the amount. :)

Answer:

Add up all the numbers then divided by how many numbers there is and the you'll get your answer.

Example:

70+80+75+85+90=400

he temperature at noon on a winter day was 2 °F. By 6 p.m., the temperature had dropped to −9 °F. Write a subtraction expression
nydimaria [60]

Based on the starting temperature and the new temperature, the relevant expression would be<u> 2 - (-9) </u>

To find the number of degrees the temperature has changed by, use the following equation:

<em>= Starting temperature - Current temperature </em>

Starting temperature = 2°F

Current temperature = -9°F

The equation becomes:

<em>= 2 - (-9)</em>

In conclusion, the expression would be 2 - (-9)

I need help with slope (8th grade)
Triss [41]

Answer:

(y1-y2)/(x1-x2)

Step-by-step explanation:

if you have two points from the graph then you can use them to find the slope, for example:

(2,3) and (0,5)

you would take the first point and put it in a fraction (and the second point) but the x goes on the bottom and the y goes on the top:

3/2 and 5/0

Next you put them together minusing one of the equations, but make sure that the two coordinates line up (it doesn't matter which one, in the order):

3-5/2-0

Then you solve:

-2/2

-1

which means that -1 is the slope for this

(the "/" is a fraction bar, in case you didn't already know that)
