Answer:
(X,Y)(18,12)
Step-by-step explanation:
x + y = 30
2x + 4y = 84
___________
2x+2y=60
2x+4y=84
_________
-2y=-24/-2y
y=12
2x+4(12)=84
2x+48=84
2x=84-48
2x/2=36/2
X=18
Answer:
g
Step-by-step explanation:
g
Let x= the total volume of liquid the bottle can hold.
Since 40% of the liquid is water, then .4x = 1L
Then you solve for x.
0.4x=1L
0.4x/0.4 = 1L/0.4
x = 2.5 L
So we have the total volume of the bottle which is 2.5 L.
Now, let the number of liters of lemon juice be y.
y=0.6x
So the equation would be x = 0.4x + y
or simply, x = .4x + .6x
Solve for y.
<span>y= 0.6(2.5L)
y= 1.5L</span>
So the amount of lemon juice in the bottle is 1.5 L.
The answer for this one is C
