11x -7y= -14 (1)
x -2y= -4 (2)
Multiply (2) by 11, we have:
11x -22y= -44 (3)
Take (1)-(3), we have:
(11x-11x)+ (-7y-(-22y))= -14-(-44)
⇒ -7y+22y= -14+44
⇒ 15y= 30
⇒ y= 30/15
⇒ y= 2
x= -4+ 2y= -4+ 2*2= 0
The final answer is x=0, y=2~

Answer:72
Step-by-step explanation:6 x 12=72
The answer is D because the difference of the X and Y of both coordinates is 1, 3. If you halve that (0.5, 1.5) then add that to your first point (2, 2) then you get (2.5, 3.5) which is the same as (5/2, 7/2).
Answer:
Sven would type 2280 words every 40 minutes.
Step-by-step explanation:
Multiply 57 by 40 and that should get you 2280.
Now, if it was truly an hour, you would multiply 57 by 60. The answer should be 3420.
