Solve each equation 7|9n+10|=70

Answers

Answer 1
Answer:

Hi


7|9n+10|=70

First divide both sides by 7

7(|9n+10|)/7= 70/7

|9n+10|=10

Now we need to find the absolute value

|9n+10=10

We know that either 9n+10=10 or 9n=10=-10

We have to possibility

The first possibility is

9n+10=10

Now we need to subtract 10 to both sides so we can find the value for n for the possibility 1

9n+10-10=10-10

9n=0

Now divide both sides by 9 so we can find the value for N

9n/9=0/9

n= 0

Now let's go for possibility 2

9n+10=-10

We gonna do the same thing for possibility 2 by subtract 10 from both sides

9n+10-10=10-10

9n=-20

Divide both sides by 9 so we can find the value for N

9n/9=-20/9

n= -20/9

Answer ; N=0 or N=-20/9


I hope that's help and good luck :)

Mabel measured an angle on her math worksheet with her protractor. The angle measured 39°. If she were to draw an angle which was supplementary to the angle on her worksheet, what should that new angle measure? A. 141° B. 51° C. 129°

Answers

The angle supplementary to the angle 39° Mabel measured is C. 129°.

What are supplementary and complementary angles?

When the sum of the two angles is 180° they are said to be supplementary.

When the sum of the two angles is 90° they are said to be complementary.

Given, Mabel measured an angle on her math worksheet with her protractor. The angle measured 39°.

Therefore, The angle supplementary to the angle she measured is,

= (180 - 39)°.

= 129°, As the sum if the sum of two angles are supplementary their sum is

180°.
