Answer:

30% as a decimal is 0.30.

Step-by-step explanation:

Simply, convert the percentage into fraction form. To convert a percentage into fraction form, you must have a denominator of 100 and 30 in the numerator. Then, simplify. At last, convert. When you convert, you must get a result of 0.3 or 0.30. Below is the conversion.

30% = 30/100 = 0.30

Hence, 30% as a decimal is 0.30.

If x2 + y2 = 38 and x - y = 2, then what is x? If there are two possible answers, then enter the larger of the two.

Ket [755]

If x-y=2 then x=2+y

And if you insert that in the first equation

$(2 + y) {}^{2} + y {}^{2} = 38$
$4 + 4y + y {}^{2} + {y}^{2} = 38$
$2y {}^{2} + 4y - 34 = 0$
$y = - 1 + \sqrt{17}$
Or
$y = - 1 - \sqrt{17}$

The first one is bigger so the answer is

$y = - 1 - \sqrt{17}$
