Select the correct answer.
andrew-mc [135]

Answer:

OPTION C

Step-by-step explanation:

We have the following rules:

$ \sqrt[a]{x} = x^{\frac{1}{a} $    and

$ x^a . x^b = x^{a + b} $

OPTION A: $ x \sqrt[7]{x} $

= $x . x^{\frac{1}{7} $

= $ x^{1 + \frac{1}{7} $

$ = x^{\frac{8}{7} $ $ \ne x^{\frac{9}{7} $

So, it can be eliminated.

OPTION B: $ \bigg ( \frac{1}{\sqrt[7]{x}} \bigg )^9 $

= $ \bigg ( \frac{1}{x^{\frac{1}{7}}} \bigg )^9 $

= $ \bigg ( x^ {\frac{-1}{7}} \bigg )^9 $

= $ x^{\frac{-9}{7}} $

So, this option is also eliminated.

OPTION C: $ x . \sqrt[7]{x} $

= $ x . x^{\frac{1}{7}} $

= $ x^{1 + \frac{1}{7}} $

= $ x^{\frac{9}{7}} $

So, OPTION C is the answer.

The first number plus the second number equals 83, the first number
timama [110]

Answer:

I hope this helps

Step-by-step explanation:

So the way to handle a problem like this is to rewrite the three numbers in terms of their relationship to one of the three numbers.  Let's call the numbers x, y, and z, where x is the first number, y is the second, and z is the third.

We know x + y + z = 83.

Since the third number is twice the second, we say that z = 2y.

Since the second number is seven less than the first, we say that y = x - 7.  We can rewrite this as x = y + 7.

Now all three can be written in terms of y.

x + y + z = 83

(y + 7) + y + 2y = 83

4y + 7 = 83

4y = 76

y = 19

The second number is 19.  The first is 19 + 7 or 26, and the third is 2 times 19 or 38.

A check reveals that 26 + 19 + 38 = 83.
