The required proportional amount of water is 15 gallons. Option B is correct.

What is proportionality?

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
Let the amount of water be x and the amount of bleach be y,
According to the question,

y =kx,
And we have given k = 1/3
y = x/3

Now, put y = 5,
5 = x/3
x = 5×3
x = 15 gallons

Thus, the required proportional amount of water is 15 gallons. Option B is correct.

Answer:

6 < x < 30

Step-by-step explanation:

The top and bottom triangles have two congruent sides with different included angles.

AB = AD and AC is common side.

The greater angle has greater opposite side.

The ∠BAC is greater than the ∠DAC as opposite side of the first (22) is greater than the opposite side of the second (16).

The ∠DAC must be greater than zero but smaller than 48°.

Required inequality is:

0 < 2x - 12 < 48 12 < 2x < 60 6 < x < 30

So x has a value between 6 and 30

Answer: 6 < x < 30

Step-by-step explanation:

0 < 2x - 12 < 48

12 < 2x < 60

Using a system of elimination is easy:

Bring the two equations up.

[tex]-6x + 9y = -12\\8x - 9y = -8\\[/tex]

Since we have 9y and -9y, they cancel each other out.

We now have:

[tex]-6x = -12\\8x = -8\\[/tex]

Now solve for x.

1. x = 2

2. x = -1.
