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.

The angles 3x+6 and 5x + 6 are supplements. What are the two angles
yarga [219]

Answer:

x = 21

Step-by-step explanation:

<u>Step 1:  Make an expression</u>

Since they are supplements, that means that they add up to 180 degrees.

3x + 6 + 5x + 6 = 180

<u>Step 2:  Combine like terms</u>

3x + 6 + 5x + 6 = 180

(3x + 5x) + (6 + 6) = 180

8x + 12 = 180

<u>Step 3:  Subtract 12 from both sides</u>

8x + 12 - 12 = 180 - 12

8x = 168

<u>Step 4:  Divide both sides by 8</u>

8x / 8 = 168 / 8

x = 21

Answer:  x = 21
