Answer:

Step-by-step explanation:

If this question is 12 is 30% of what number then you would solve it as such:

\frac{30}{100} = \frac{12}{x}

Note that you can rewrite any percent as the value that they give you over 100, and also since the question says that 12 IS 30% then 12 should be directly across 30% in the proportion itself (as shown above).

This gives:

30x = 1200

Dividing by 30 gives us that

x = 40

So 12 is 30% of 40.

Can someone solve this for me with their explanation please?
Lana71 [14]

First you want to subtract 36

so it looks like this \sqrt[4] {(4x+164)^3}=64

Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)

{(4x+164)^3}=64^4 which is equal to {(4x+164)^3}=16777216

Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]

Then you end up with the equation 4x+164=256

Then subtract 164 to both sides

4x=92

then divide 92 by 4

Then you get x=23
