What is the value of X ?

harkovskaia [24]

The sum of all the angle measures is 180 degrees, now lets set up some equations:

$(3x-35)+(x-35)+x = 180\\5x - 70 = 180\\5x = 110\\x = 22$

Thus x = 22

Hope that helps!

Simplify the square root (Picture provided)

Elodia [21]

For this case we must find the value of the following expression:

$\sqrt {8 ^ {17}}$

We have to:

$8 ^ {17} = 8 ^ 1 * 8 ^ {16}$

Substituting:

$\sqrt {8 * 8 ^ {16}}$

By definition of properties of powers and roots we have:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

So:

$8 ^ {\frac {16} {2}} * \sqrt {8}\\8 ^ 8 * \sqrt {8}$

So we have to:

$\sqrt {8 ^ {17}} = 8 ^ 8 * \sqrt {8}$

Answer:

$8 ^ 8 * \sqrt {8}$

Option A

There are 8 green tokens in the bag . The ratio of green tokens to black tokens is 4 for every 1 find the number of black tokens

Cloud [144]

Answer:

the number of black tokens in the bag is 2

Step-by-step explanation:

The computation of the number of black tokens in the bag is as followS

Given that

There is 8 green tokens

and, the ratio of green tokens to black tokens is 4:1

So let us assume the black tokens be x

So,

$\frac{8}{x} = \frac{4}{1}$

Now do the cross multiplication

x = 2 tokens

Hence, the number of black tokens in the bag is 2
