Answer:
both are 75 degrees
Step-by-step explanation:
the angles add up to 180, as they are also vertical angles
Answer:
b=c since they are vertical angles, b=75 and c=75
Step-by-step explanation: The angle opposite of the given is the same (105) that gives you two measure. Add 105+105 to get 210. A set of vertical angles=360 degrees, take away 210 from 360 to get the measure of b+c. Divide that by two to get the measure of either b or c.

Carla and Andrew have 29 chocolate chip cookies. Andrew has 8 more than twice Carla’s cookies. How many cookies does each person have?
Answers
Step-by-step explanation:
29 cookies
Carla has X cookies

7/2x + 1/2x = 10 + 9/2x
Answers
Answer:
x=-1/20
Step-by-step explanation:
7/2x+1/2x=10+9/2x
We move all terms to the left:
7/2x+1/2x-(10+9/2x)=0
Domain of the equation: 2x!=0
x!=0/2
x!=0
x∈R
Domain of the equation: 2x)!=0
x!=0/1
x!=0
x∈R
We add all the numbers together, and all the variables
7/2x+1/2x-(9/2x+10)=0
We get rid of parentheses
7/2x+1/2x-9/2x-10=0
We multiply all the terms by the denominator
-10*2x+7+1-9=0
We add all the numbers together, and all the variables
-10*2x-1=0
Wy multiply elements
-20x-1=0
We move all terms containing x to the left, all other terms to the right
-20x=1
x=1/-20
x=-1/20
Answer:
[tex] \frac{7}{2} x + \frac{1}{2}x = 10 + \frac{9}{2} x \\ ( \frac{7}{2} + \frac{1}{2} - \frac{9}{2} )x = 10 \\ \frac{ - 1}{2} x = 10 \\ - x = (10 \times 2) \\ x = - (10 \times 2) \\ x = -20[/tex]

Which of the following equations , in it's simplest form , will be equivalent to 3x+2+(-5)?
A: 2+3x+5. B: x-1+x-2+x C: -3-3x-1+x
D: 3-3x
Answers
Answer:
The correct answer would be B: x-1+x-2+x
Step-by-step explanation:
First, you would do 2+(-5), from the given equation. Then, it could be simplified to 3x-3. Then, looking at B, you would add the like terms, meaning you would add all the x´s together, and the whole numbers together, giving you 3x-3. I hope I made this easy to understand for you!

First you need to find the slope of the two points.
The slope is -2
Then you use the slope intercept form to find the y intercept.
y=2x+b
You then have to plug in the x and y points.
6= -2(2) + b
6= -4+b
b=10
Lastly write using the slope intercept
y= -2x+10
