Susan keeps track of the high and low temperatures every day for a week. The following table shows her data what is the average

uysha [10]

Answer:

10.75

Step-by-step explanation:

To get the average, we always SUM UP all the numbers and divide by the number of numbers.

We do this for "change" row since we want average of "change".

Let's add up all the changes:

11 + 12 + 10 + 10 + 11 + 10 + 11 = 75

How many numbers are there?

There are 7 numbers

Now, the average:

Average = Sum/Number of Numbers

Average = $\frac{75}{7}=10.75$

The average = 10.75

Solve the following proportions 3/x-3=8/2x+6 X=

Rzqust [24]

Answer:

Step-by-step explanation:

3/(x-3) = 8/(2x+6)

or, 8x - 6x = 24 + 18

or, 2x = 42

or, x = 42/2
