55% of what number is 330? pls help meee

600

Step-by-step explanation:

Assume x=target number

55%(x)=300

55%=0.55

0.55x=300

x=300/0.55

x=600

Answer

600

Step-by-step explanation:

Here is the formula/format:

Part             %

    =    

Whole         100

We are trying to find the "whole" in this case, so I did:

330            55

  =    (this says that 55% of the number we are looking for is 330)

x                100

Then, I cross multiplied and got: 55x= 33,000

From there, I divided 33,000 by 55 (inverse operations) to get x = 600.

I hope this helps! :)

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
