Answer:
A and C
Step-by-step explanation:
Calculate the concentrations for each mixture.
Mixture A:
(4 teaspoons salt) / (2 cups water) = 2 teaspoons/cup
(0.25 cup sugar) / (2 cups water) = 0.125 cup/cup
Mixture B:
(3 teaspoons salt) / (1.5 cups water) = 2 teaspoons/cup
(0.2 cup sugar) / (1.5 cups water) = 0.133 cup/cup
Mixture C:
(2 teaspoons salt) / (1 cups water) = 2 teaspoons/cup
(0.125 cup sugar) / (1 cups water) = 0.125 cup/cup
Mixtures A and C have the same concentration.
Answer:
(3,6)
Step-by-step explanation:
Collect like terms
y -5x = -9
y + 2x = 12
Using elimination method
Subtract equation 2 from equation 1
y - 5x = -9
y + 2x = 12
---------------
0. -7x = -21
Divide both sides by -7
-7x = -21
---- -----
-7 -7
x = 3
Substitute x=3 into equation 1
y = 5(3) - 9
y = 15 - 9
y = 6
Solution is (x,y) = (3,6)
