Remember yo can do anything to an equation as long as you do it to both sides
so
remember distributive property
a(b+c)=ab+ac
so first distribute
2(3x)+2(-9)=18x
6x-18=18x
minus 6x both sides
-18=12x
divide both sides by 12
-18/12=x
-9/6=x
-3/2=x
easier way is to first divide both sides by 2
x=-3/2
Answer:
I think that5 it is the secend one
Step-by-step explanation:
Answer: The mean is 4, median is 4, no mode, range is 4
Step-by-step explanation:
<u>mode</u> is adding all the numbers and subtracting by the total amount of whole numbers
<u>median</u> is putting the numbers in a line ex.( 2, 6, 4, 5, 3) and crossing out left to right until theres one number left
<u>mode</u> is which ever number is repeated the most
<u>range</u> is the biggest number subtracted by the smallest number
Every whole number is a rational number because whole numbers can be written as fractions.
