Answer:

Step-by-step explanation:

The angles 7x° and (x + 20)° are supplementary angles.

Supplementary angles add up to 180°.

Therefore we have the equation:

7x + (x + 20) = 180

7x + x + 20 = 180 <em>subtract 20 from both sides</em>

8x = 160 <em>divide both sides by 8</em>

x = 20

Answer:

The best fit line is $y = 1.671x + 4.699$

Step-by-step explanation:

We are given,

The table representing the number of miles run in different weeks is,

Week Miles Run

1 5

2 8

4 13

6 15

8 19

10 20

Using the linear regression calculator, we see that,

<h3>The equation of the line best fit for the data is $y = 1.671x + 4.699$ .</h3>

Math the equation to the solution type

Margarita [4]

Answer:

Step-by-step explanation:

1. 6x + 10 = 6x - 8

10≠-8

no solution

2. 6x + 8 = 2x - 6

4x + 8 = -6

4x = -14

x = -14/4= -7/2 one solution

3. 9x - 27 = 9x - 27

0 = 0 All real no. infinitely many solution

Describe a real life multiplication situation for which an estimate makes sense

Drupady [299]

If you are trying to create a garden of potted plants, you would find out how much soil each pot needs/holds and multiply that by how many pots you plan to use. then you would go to the store for potting soil, which let’s say came in smaller packs and you need to purchase multiple. use multiplication estimation to estimate how many bags you’d need.
I know this is a dumb example...sorry this is one I remember from my fourth grade math teacher ahah
