She has 11 friends,
20 of the balls=5 friends and the rest =6 friends. I may be wrong so check this for yourself to be sure. :)
80 x 40 is 320. I know 80 x 40 is 320 because 80 + 80 + 80 + 80 is 320. I also know 80 x 40 is 320 because 8 x 4 is 36. If you pretend the 0 is not there it’s 8 x 4. I know you can get the answer quicker that way because it’s just times tables.
Answer:
(x, y) = (8, -3)
Step-by-step explanation:
You can substitute for x in the first equation:
3(-3y -1) +3y = 15
-6y = 18 . . . . . add 3 and simplify
y = -3 . . . . . . . divide by -6
x = -3(-3) -1 = 8 . . . . find x using the second equation
The solution to this system of equations is (x, y) = (8, -3).
