Mathematics

Answer: All Real Numbers

Explanation: Notice that when you try to put your variables together on one side of the equation by subtracting 4y from both sides, the y terms cancel out on both sides and we no longer have a variable in the equation.

Notice however that we are left with the statement 12 = 12.

Since 12 = 12 is a true statement, we say that

the solution to this equation is all real numbers.

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

Isolate for each variable.
1. z= 6 - 10
z= -4

2. y= 48/8
y=6

3. q= 1+12
q= 13
4. 18 x 2= a
36= a
5. r= 7 x 3
r= 21

I think you can try the rest :)
