QR IS 23.8! Just subtract 68.4-44.6. The answer is right because 44.6+23.8=68.4
What? This isn’t really a question!
The given options are:
- (A)x+y = 20
- (B)7 apps and 14 movies
- (C)x-y= 20
- (D)y=-x+ 20
- (E)8 apps and 12 movies
- (F)xy= 20
Answer:
- (A)x+y = 20
- (D)y=-x+ 20
- (E)8 apps and 12 movies
Step-by-step explanation:
If Elizabeth has a combined total of 20 apps and movies.
Where:
Number of apps=x
Number of Movies =y
Then:
Their total,
If we subtract x from both sides
x+y-x=-x+20
In Option E
8 apps and 12 movies add up to 20. Therefore, this could also apply.
The entire angle is a 90 degree angle.
Subtract the entire angle from what is given to find x.
90-28=62
x=62
