Answer:
400ml of juice
Step-by-step explanation:
1 litre of water = 100ml of juice
4 litres of water =? ml of juice
to get from 1 litre to 4 litre of water you multiply by 4,so you do the same for the juice and multiply the juice by 4.
100×4=400
4 litres of water = 400ml of juice
–x + y = –3 (a)
3x + 2y = 9 (b)
Lt's eliminate y , by multiplying a) by -2
-2(–x + y) = -2(–3) → +2x - 2y = +6 (c). Now add (c) to (b)
+2x - 2y = +6 (c).
3x + 2y = 9 (b)
----------- --------
5x + 0 = 15 and x = 15/5 and x = 3
To find y, plugin the value of x in any of the equation, sat (a):
–x + y = –3 (a) → -3 + y = -3; y = -3+3 → y = 0
So the solution is (3,0) Answer C
I’m pretty sure it’s 1 1/3
