1) Write An Equation That Can Be Used To Solve For The Missing Angles. (5pts)2) Then Solve The Equation

Answers

Answer 1
I don’t know how I should find the missing angles. But I can solve for X. So first we need to combine like terms so we add 2x, x and x which gives us 4x. And we set up our problem like this: 4x + 24=180. So we then subtract 24 from 180 and get 156 then divide 4x and 156, which leaves us with x=39

Identify the slope - eighth grade math

Answers

Answer:

-11 and (0,6)

Slope = -11

B = (0,y-intercept) = (0,6)

-Chetan K

it’s d ! -11 is your slope since its next to the x and your y-intercept is 6 aka b in y=mx+b

Answers

Answer:

Step-by-step explanation:

1. -7 = w + 5

w = -12

(-12 + 5 = -7)

2. -4p + 38 = 10

           -38     -38

-4p = -28

/-4        /-4

p = 7

3. -3 1/2 = -1 1/4b

   /1.25      /1.25

-2 4/5 = -b

2 4/5 = b

or

2.8 = b

Answer:

Step-by-step explanation:

Question 1:

-7 = w + 5

- 5        - 5

-12 = w      

w = -12

Question 2:

-4p + 38 = 10

      - 38   - 38

-4p = -28

-----    -----       fraction bar... -4p divided by -4, -28 divided by -4

-4       -4

p = 7

Question 3:

-3 1/2 = -1 1/4b

- 7    =  - 5

-----      ----- b

 2          4

4        -7          -5          4

Could somebody please help me find the answers for 'x' for these pictures?
**Please let me know which one you solved along with the answer**

Answers

Answer:

Pic 1: [tex]x=31[/tex]

Pic 2: [tex]x=20[/tex]

Step-by-step explanation:

Picture 1:

[tex]2x+x-3=90\\3x-3=90\\3x=93\\x=31[/tex]

First, add the 2x and x together for 3x

Then add 3 to both sides of the equation

Finally, divide each side by 3.

Picture 2:

[tex]7x+x+20=180\\8x+20=180\\8x=160\\x=20[/tex]

First, add 7x and x together for 8x

Then, minus 20 from both sides of the equation

Finally, divide each side by 8.

Step-by-step explanation:

First picture

We can make an equation with this

2x+x-3=90

3x=93

x=31 degrees

Second picture

We can make and equation

7x+x+20=180

8x=160

x= 20
