4 x (3+6) = 12 + 24 ---->Distributive
3 + ( 8 + 2) = 3 + (2 + 8) ---> Commutative
6 x (7 x 3 ) = (6 x 7 ) x 3 --->Associative
Its A a single outlier causes the upper quartiles to move close together
im pretty sure
Answer:
52
Step-by-step explanation:
180 - 127 = 53
53 + 75 = 128
180 - 128 = 52
Answer:
the answer would be 28.
Step-by-step explanation:
you're multiplying the top and bottom by 7. 3 *7=21 for the bottom
4*7 = 28 for the top
Hope this helps

10x+2y=18
10x-7y=-18
Multiply the second one by -1
-10x+7y=18
Then add the two equations
10x+2y=18
+-10x+7y=18
----------------
9y=36
y=4
Plug that back into one of the equations above and solve for x
10x+2y=18
10x+2(4)=18
10x+8=18
10x=10
x=1
so your answer is x=1 and y=4 or (1,4)
