X=23
39÷3 =13
x - 10 = 13
x = 23
Answer:
1.) 22+(33+44)
2.) (5+3)+(1+9)
3.) (-a+d)+(-c+b)
Step-by-step explanation:
Associative property of addition: Changing the grouping of addends does not change the sum. For example,
(2+3)+4= 2+(3+4)
No matter how you rearrange the numbers, they will always add to the same amount.
This is fairly easy, all you need to do is write the ordered pairs for each graph, for these there are 5 ordered pairs for both.
In order to create the ordered pair all you need is this 'formula' of (x, y)
In the first graph 'input' would be the x value and output is the y value. So all you do is plug them into the formula.
(-10,-20)
(-5,-10)
(0,0)
(5,10)
(10,20)
Those are all the ordered pairs for graph A. Now just do the same thing for graph B.
Mean is 6 because once you add up all the numbers it will be 60, and dividing that number by how many you have will give you 6
Median is 5 because once you place the numbers in order, 0, 0, 1, 2, 3, 7, 9, 10, 13, 15 the middle number in the set is between 3 and 7 and once you find the mean of the two you get 5
