Answer:

C

Step-by-step explanation:

∠1 = 3x + 18            {Vertically opposite angles}

∠1  + 28° = 90

3x + 18 + 28 = 90

3x + 46 = 90

3x = 90 - 46

3x = 44

x = 44/3

x = 14 \dfrac{2}{3}

Answer:

  a.  x + 4y = 160

  b.  160

  c.  40

Step-by-step explanation:

a. We can define the variables as ...

  x = number of 1/2-liter bottles

  y = number of 2-liter bottles

For the total number of liters to be 80, we require

  1/2x + 2y = 80

We can multiply this by 2 to eliminate the fraction.

  x + 4y = 160

__

b. The x-intercept is 160. It is the number of 1/2-liter bottles required when no 2-liter bottles are used.

__

c. The y-intercept is 40. It is the number of 2-liter bottles required when no 1/2-liter bottles are used.
