Hunter-Best [27]

First you had to subtract by seventeen from both sides of equation form.

17+p-17=7p-13-17

Then simplify.

p=7p-30

Next, subtract by seven-p from both sides of equation form.

p-7p=7p-30-7p

Simplify.

-6p=-30

Then you divide by negative six from both sides of equation form.

\frac{-6p}{-6}= \frac{-30}{-6}

And finally, simplify by equation.

-30/-6=5

Final answer: \boxed{p=5}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

Solve for x round to nearest tenth of a degree
Lena [83]

To find the measure of angle NLM which is x, we must use trigonometry.

In this case we use the sine function:

    sin(x) = (side opposite angle NLM) / (hypotenuse)

    sin(x) = \frac{4.9}{7.5} \\x = sin^{-1}(\frac{4.9}{7.5})\\x= 40.8 degrees

Hope that helps!
