If you need an equivalent expression just make a simple problem like 30+4=4+30 then add all the complicated stuff needed to complete the problem <span />
Answer:

Step-by-step explanation:
Total number of the students in the pep squad = 12 students
The number of the students wearing white shirts = 3 students
The number of the students wearing blue shirts = 6 students
Either white or blue shirts indicate that the students wearing white shirt or blue shirt.
Thus, number of students wearing either white or a blue shirt = 3 + 6 students = 9 students
So,
The fraction is:- 
Firstly, the height increased.
Before restoration the height was 56.84*cos(5.5°).
After restoration : <span>56.84*cos(3.99°).
The difference is :
</span>56.84*cos(3.99°)-56.84*cos(5.5°)=56.84(cos(3.99°)-cos(5.5°))=56.84*0.0022=0.1239≈0.124 - the answer
Answer:

Step-by-step explanation:
First, find the <em>rate of</em><em> </em><em>change</em><em> </em>[<em>slope</em>]:

Then plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope</em><em> </em><em>Formula</em><em> </em>since you get it done much swiftly that way. It does not matter which ordered pair you choose:
−4 = ⅓[−12] + b
−4

_______________________________________________
−3 = ⅓[−9] + b
−3

**You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.
