The equation to your question would be P =10(c)+20. meaning 10 pencils in each box multiplied by the number of boxes (c) plus the 20 pencils the teacher gives her will equal the number of pencils (P) she has altogether. (C stands for the number of boxes and P stands for pencils)
so lets say she has 3 boxes. well, c stands for boxes soooo...... all you have to do is plug in 3 were c is. giving you this equation P = 10(3)+20. then all you have to do is solve. P = 10(3)+20
10 times 3 = 30 so P = 30+20
then add 30 and 20 P = 50 she has 50 pencils altogether
(remember this is just an example, 50 pencils is NOT the answer to your question. but you can use the equation i gave you to find your own answer!) :) Hope this helps!!
A reflection is a transformation where the mirror image of a figure is shown directly opposite its line of reflection.
To find an image that has been reflected across the line y = x, switch the x- and y-coordinates.
Therefore, the rule for reflecting an image across the line y = x can be described as (x, y) → (y, x).
Now, apply rule to coordinates ABC:
A': (2, 3)
B': (1, -4)
C': (-2, -3)
Answer: i think it is 20.00$

Answer:
a
Step-by-step explanation:
Alright! In order to solve this, you have to isolate your variable, which is b. To do that you'd first have to add one to both sides in order for you to be left with:
[b/3 = 5]
Since 3 is in the denominator, you multiply both sides by 3 in order to get rid of it. In the end you get
[b = 15]
The answer is 15.
