7/30 x 100 = approx 23.3%
X could either be 4 or 5, depending on which x the question asks. If you have to chose one answer go with 5 because it's associated with the y.
You do 3/5 minus 3/5 which cancels out to 0. Then you do 6 minus 4 which is 2. The answer is 2.
Answer is D or the last choice
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.
