Answer:

-3

Step-by-step explanation:

First you subtract the first equation from the second one and you get:

3x  + 3y   =  3

x +  y   =  1  

y =  1 - x

Then you use it on the first equation

888x  +  889 (1 - x)  =  890

888x  +  889  -  889x  =  890

-x = 1

x = -1

y = 1 - x

y = 1 - (-1) = 2

Now that you have those two numbers, we have to subtract the value of x from y:

x - y

-1 - 2 = -3

Hope this helps bro

What is the mean of the values in the stem-and-leaf plot?<br><br><br> Enter your answer in the box.
BartSMP [9]

Answer:

The mean is the average of a set of data.

Example:

To find the mean, add up all of the numbers in the set and divide by the number of values that you added.

35 + 36 + 37 + 38 + 40 + 40 + 41 + 42 + 43 + 55 + 55 + 55 + 56 + 57 + 58 + 59 = 747

Then, divide by the number of values, which is 16.

747/16=46.68

The sum of three numbers is -44.84. One of the numbers is 26.6. The other two numbers are equal to each other. What is the value
docker41 [41]
A+b+c=-44.84

a=26.6
b=c

26.6+b+b=-44.84

2b=-44.84-26.6

b=-35.72


So, a=26.6, b=-35.72, c=-35.72
