Add 8π to both sides of the equation to get:

$x - 8\pi + 8\pi = \pi + 8 \pi$

$\boxed{x = 9 \pi}$

We have found that x = 9π. Remember that in solving problems like these with pi that it can often be helpful to treat pi as a variable.

Which expression is equivalent to -32 to 3/5 power

levacccp [35]

<u>Answer:</u>

<u>Step-by-step explanation:</u>

We are given the following expression and we are to find the simplest form of this expression:

$- 3 2 ^ { \frac { 3 } { 5 } }$

First of all, we will factor the coefficient:

$3 2 = 2 ^ 5$

Rewriting it as:

$- ( 2 ^ 5 ) ^ { \frac { 3 } { 5 } }$

Applying the exponent rule $(a^b)^c = a^{bc}$ to get:

$-2^{5.\frac{3}{5}}=-2^3$

$-2^3=-8$

Answer:

The weighted average is of 69.94.

Step-by-step explanation:

Weighted average:

The weighed average is found multiplying each grade by its respective weight.

The grades, and weights are:

67 on the lab, with a weight of 23% = 0.23

69 on the first major test, with a weight is 21.5% = 0.215

85 on the second major test, with a weight is 21.5% = 0.215.

63 on the final exam, with a weight of 34% = 0.34.

Weighted average:

$A = 0.23*67 + 0.215*69 + 0.215*85 + 0.34*63 = 69.94$

The weighted average is of 69.94.
