Answer:

x = - 3

Step-by-step explanation:

Given the 2 equations

y = $\frac{1}{3}$ x + 7 → (1)

y = 3x + 15 → (2)

Since both equations express y in terms of x, equate the right sides

3x + 15 = $\frac{1}{3}$ x + 7

Subtract $\frac{1}{3}$ x from both sides

$\frac{8}{3}$ x + 15 = 7 ( subtract 15 from both sides )

$\frac{8}{3}$ x = - 8 ( multiply both sides by 3 )

8x = - 24 ( divide both sides by 8 )

x = - 3

The dose of a strong cough medicine might be which of the following? 2mL, 200mL, 2L

Margarita [4]

To find the answer,we can picture how much the above value is by objects in real life.

2mL = about two drops of water

200mL = about a carton of milk/ a box of ornage juice

2L = 2000 × 10 mL = 20000 mL = The bottle of drinks that are in family/party size.

As we only take in small dosages of medicine, the best option would be 2mL.

Hope it helps!

Total number of faculty is 136. There are 6 professors to every 11 lecturers. How many professors are there

laila [671]

Answer:

The Total number of Professors = 48

Step-by-step explanation:

Given as,

The total number of Faculty = 136

And the Ratio of Professors to Lecturers = 6 Ratio 11

Now According to question

Professors : Lecturers = 6 : 11

So, Let the Number of Professors = 6x

And The Number of Lecturers = 11x

∴ 6x + 11x = 136

Or, 17x = 136

Or, x = $\frac{136}{17}$ = 8

Hence, the number of Professors = 6 × 8 = 48 Answer

X and y are positive integers. explain why incorrect to claim that

dedylja [7]

You can find counterexamples to disprove this claim. We have positive integers that are perfect square numbers; when we take the square root of those numbers, we get an integer.

For example, the square root of 1 is 1, which is an integer. So if y = 1, then the denominator becomes an integer and thus we get a quotient of two integers (since x is also defined to be an integer), the definition of a rational number.

Example: x = 2, y = 1 ends up with $\frac{2}{\sqrt{1}} = \frac{2}{1}$ which is rational. This goes against the claim that $x/\sqrt{y}$ is always irrational for positive integers x and y.
