Answer:
m∠R= 87°
Step-by-step explanation:
The angles in a polygon add up to (n-2)180
(5-2)180= 540°
You can set up an equation to add all the angles together equaling 540°.
Once you solve for x, plug that back into the formula for the angle of R(7x-11)
B.32 You get this because a square is perfect, which means it's equal on all sides. So 8x4=32
8 - 4(-x + 5)
As you already know, in order to find the equivalent expression to our already given one, we have to simplify it first :)
8 +4x - 20
**Remember that a negative times a negative is always a positive!!**
Add like terms.
4x + (8 - 20)
Simplify.
4x + (-12)
Get rid of parenthesis.
4x - 12
Look at our answer choices.
Our answer is a. 4x - 12

Answer:
The box contains 20 milk chocolates.
Step-by-step explanation:
Given that the chocolate box has milk chocolates and dark chocolates in a ratio of 2 milk chocolates for every 3 dark, and the total number of chocolates in the box is 50 units, to determine how many milk chocolates are in the box. it is necessary to perform the following calculation:
50 / (2 + 3)
50/5
10
Milk chocolates: 2 x 10 = 20
Dark chocolates: 3 x 10 = 30
Therefore, the box contains 20 milk chocolates.
The answer is 345 :) hope this helps u
