It is a composite number and it is written as 7*3*5*2
Analyze perfect cubes:
1^3 = 1
2^3 = 8
3^3 = 27
Since 12 is between 8 and 27, cube root of 12 is between 2 and 3.
You also know it is much closer to 2, since 12 is much closer to 8.
A good guess would be 2.25
(2.25)^3 = 11.39
This is close but slightly less than 12.
When you use your calculator you should get 2.2894.
Here we have an equation in one variable "w"
What we need to is getting rid of (-1/25) that is multiplied by "w"
right?
so we need to multiply both sides by "-25", so we get:
so, you can choose the first choice confidently....
I hope you got
the idea
Answer: M= -5
Step-by-step explanation: -5x+12
Well, the way you wrote it ... 22/7 ... it's not a decimal at all.
It's an improper fraction. But I understand what you mean.
Remember ... a fraction is a short way to write a division problem.
Whenever you see a fraction, it means
(the top number) divided by (the bottom number) .
If you take your pencil and paper, or your calculator, and do
the division '22' divided by '7' ... very easy to do; you really
should have done it on your own ... you get
3.142857...
That group after the decimal point ... the " 142857 " ... does
repeat forever. So 22/7 does produce a repeating decimal.
