Solve for N, <br><br> −2p + 6n = 5
topjm [15]

Answer:

n=\frac{1}{3}p+\frac{5}{6}

Step-by-step explanation:

In this question, you are solving for n.

Solve:

−2p + 6n = 5

We have to get "n" by itself, so add 2p to both sides.

6n = 2p + 5

Since the variable "n" has a number next to it, we have to get rid of that number in order to get our answer.

To do so, we would divide both sides by 6.

n=\frac{2}{6}p+\frac{5}{6}

Simplify the equation further.

n=\frac{1}{3}p+\frac{5}{6}

I really dont understand what to do here if you can please help
NNADVOKAT [17]

Answer:

see below

Step-by-step explanation:

The two angles form a straight line so they add to 180 degrees

5x+60   + 3x-40 = 180

Combine like terms

8x +20 = 180

Subtract 20 from each side

8x+20-20=180-20

8x= 160

Divide by 8

8x/8=160/8

x=20

5x+60 = 5*20+60 = 160

3x-40 = 3*20-40 = 20
