With B, when you add x to the -x, you cancel it out, giving you 0=0, which is true. hope it helps!

25.7 is what percen of 141?

suter [353]

25.7 is 18.23% of 141.

Step-by-step explanation:

Let,

The percent be x.

Therefore,

x% of 141 = 25.7

Changing percent into 100 and multiplying x with 141.

$\frac{141}{100}x=25.7$

1.41x = 25.7

Dividing both sides by 1.41

$\frac{1.41x}{1.41}=\frac{25.7}{1.41}\\\\x=18.23\%$

25.7 is 18.23% of 141.

Setler79 [48]

Answer:

See explanation below

Step-by-step explanation:

To find the principal square root of a number, we the number with an index of 2. The base then become the principal square root.

In the same way, we find the cube root of a number by writing the number with an index of 3 and the base becomes the cube root of the given number.

For instance:

$64=8^2\implies 8=\sqrt{64}$

$64=4^3\implies 4=\sqrt[3]{64}$
