Answer:

12°

55°

Step-by-step explanation:

∠WXY=90°

∠ZXY=∠WXY- ∠WXZ= 90° - 35°= 55°

4x+7°= 55°
4x= 48°
x= 48°/4
x= 12°

Answer:

The first question: The answer is C.12

The second question: The answer is C. 55

Step-by-step explanation:

The first question : Explanation: since WXY is 90 degrees and WXZ is 35 degrees subtract those two to get ZXY: 90 - 35 is 55

So it would like this for ZXY: 4x + 7 = 55

x = 12

So your first answer would be C. 12

The second question: Explanation: Since we got the answer for X value we substitute it in the equation: 4x12 + 7 = 55

So the second answer would be C. 55

Select the equivalent expression.

Free_Kalibri [48]

Answer:

$\frac{7^{15}}{3^{30}}$

Step-by-step explanation:

The given expression is:

$(\frac{3^{-6}}{7^{-3}})^{5}$

Moving the expression to the other side in the fraction changes its sign to opposite. A numerator with negative exponent, when written in denominator will have the positive exponent. Using this rule, we can write:

$(\frac{3^{-6}}{7^{-3}})^{5}\\\\ = (\frac{7^{3}}{3^{6}} )^{5}$

The exponent 5 can be distributed to both numerator and denominator as shown:

$(\frac{7^{3}}{3^{6}} )^{5}\\\\ = \frac{(7^{3})^{5}}{(3^{6})^{5}}$

The power of a power can be written as a product. i.e.

$\frac{(7^{3})^{5}}{(3^{6})^{5}}\\\\ =\frac{7^{15}}{3^{30}}$

So, the expression similar to the given expression and with positive exponents is: $\frac{7^{15}}{3^{30}}$
