I think, yes?
Step-by-step explanation:
Answer:
(x,y) = (2,3)
Step-by-step explanation:
y=5x-7 (i)
-3x-2y= -12
-(3x+2y)= -12
3x+2y= 12 (ii)
By putting the value of y from (i) in (ii)
3x+2(5x-7)=12
3x+10x-14=12
13x=12+14
13x= 26
x = 
x= 2
By putting the value of x in (i)
y= 5(2)-7
y= 10-7
y= 3
(x,y) = (2,3)

Answer:
Amount of frozen soup = 2500 mL
Step-by-step explanation:
We are told that tom made 5,000 mL of soup.
We are also told he packed 2.5 Litres into his kids' lunches.
Now, from conversions,
1 liter = 1000 mL
Thus,
2.5 litres = 2.5 × 1000 = 2500 mL
Now, we are told he froze the rest of the soup.
Thus;
Amount of frozen soup = total amount of soup made - amount given to kids' lunch pack.
Amount of frozen soup =
5000 - 2500 = 2500 ml
