Answer:
The ordered pair (4,1) gives a true statement for both equations.
Step-by-step explanation:
So for the first equation, x + 2y = 6. The ordered pair is (4,1). This means x=4 and y=1 because ordered pairs are in (x,y) form. First substitute the x and y values into the first equation
Let x=4 y=1
x + 2y = 6.
4 + 2(1) = 6
4 + 2 = 6
6=6. This means that the ordered pair works for the first equation.
Now, the second equation. x - y = 3.
Again, substitute the x and y values.
4 - 1 = 3
3=3. This means that the ordered pair (4,1) works for the second equation.
The ordered pair (4,1) gives a true statement for both equations.
600 + 400 milliliters = 1,000 milliliters.
However, the question is asking how many liters she drank. 1 liter = 1,000 milliliters, so that means Cathy drank 1 liter of water.
