Reason
21 + 24 = 180° [? ]
A. Addition property of equality
B. Linear pair postulate
C. Adjacency theorem
Answers
Explanation:
As the name implies, "linear pair" means the two angles combine to form a straight line of 180 degrees. Think of gluing the angles together.
As an example, let's say angle 1 was 50 degrees and angle 4 is 130 degrees. They combine to 50+130 = 180 which is a straight angle. I recommend using a protractor to help draw these angles.

Jane will rent a car for the weekend she can choose one of the two plans the first plan has an initial fee of $42 in cost of additional $.12 per mile driven the second plan has an initial fee of $55 in cost additional seven cents per mile driven
Answers
Answer:
260m
$73.2
Step-by-step explanation:
For what amount of driving do the plans cost the same?
What the cost when the two plans cost the same?
first plan = 42 + 0.12m
second plan = 55 + 0.07m
42 + 0.12m = 55 + 0.07m
collect like terms
55 - 42 = 0.12 - 0.07m
13 = 0.05m
m = 260
42 + 0.12(260) = 73.2

There was 1/3 of a box of cereal left four brothers shared it evenly write an equation to represent this problem
Answers
Answer:
1/12
Step-by-step explanation:
It is given that :
Amount of cereal left = 1/3 of a box
Number of people amongst whom the box of cereal is to be divided equally = 4
Therefore, an equation representing this problem is :
[tex]$\frac{1/3}{4} = x$[/tex]
where x = is the amount of the share each brother gets.
Therefore solving the equation, we get :
[tex]$\frac{1/3}{4} = x$[/tex]
[tex]$\frac{1}{3} \times \frac{1}{4} = x$[/tex]
[tex]$\frac{1}{12}=x$[/tex]
So, each brother got 1/12th of the cereal left.

Answer:
Blue: y = x² + 3
Purple: y = (x + 4)²
Step-by-step explanation:
The parabolas are "transformed", meaning they have been shifted on the coordinate grid. All parabolas will have the equation of "y = x²", any additional transformation will add onto that.
Blue: Looking at the red parabola, its lowest point is only three units down from the blue's lowest points. Meaning the blue parabola went only three units up. So you only have to do the "+ 3" in the equation.
Purple: Like in blue, we're gonna look at the purple's lowest point and compare it to red's lowest point. The purple parabola seems to have shifted only four units to the left. Though, instead of adding onto the equation like in the blue parabola, any changes on the x-axis will be put into parenthesis. IN ADDITION, the sign will be the opposite of what it is on the coordinate grid. For example, the purple parabola is on the -4 of the x-axis. Instead of putting "(x - 4)", we put "(x + 4)".
Try the next two problems on your own. They will be similarly structured to the two answers above. If you need more help, lemme know. :)

Step-by-step explanation:
Let x = Frank's age
2x+4+ = Charlie's age
x+3+ = Bob's age
9 = Bob's age
x+3=9
x=6
2x+4=2⋅6+4
2x+4=12+4
2x+4=16
Charlie is 16
