7x-5y=21 when x=4 from the coordinate point of (4,y)
Next,
7x-5y=21
Substitute x with 4
7(4)-5y=21
28-5y=21
Add 5 to each side
28-5y+5y=21+5y
28=21+5y
Subtract 21 to each side
28-21=21+5y-21
7=5y
Divided 5 to each side
7/5=5y/5
y=7/5
Or
y=1 2/5
Check:
7x-5y=21
Substitute x with 4 and y with 7/5
7(4)-5(7/5)=21
28-7=21
21=21. As a result, (4,7/5) is your correct answer. Hope it help!
The answer is 23 because I know this answer.
What u have to do is find the absolute value and since it is in different quadrants you subtract so it would be 3 the expression would be |-6|-|3|=X
<u>Answer:</u>
On day lily will first water her flower and trees together.
<u>Explanation:</u>
Lilly waters her flowers every 4th day and her trees every 11th day
So the first day when she will water flower and trees together is the LCM of 4 and 11.
LCM is the Least Common Multiple of the given numbers.
So here the LCM of 4 and 11 is
So the first day will be on day (after 1 month 14 days).
Answer:
