This question is just a question targeted towards puzzling the solver. It is infact a very easy problem. In the given question the information's provided should be very minutely watched. First information says that there is an unknown number. The problem revolves around this unknown number and various information's show that this number is always connected with the majority information's provided.
Let us assume the unknown number = x
Then
2x -4 = x - 10
2x - x = - 10 + 4
x = - 6
So the unknown number is -6.

Which ordered pair is in the solution set of 6x + 4y ≤ −2?

Nutka1998 [239]

Answer:

x≤ −2/3y + −1/3

Step-by-step explanation:

because...

Step 1: Add -4y to both sides.

6x + 4y + −4y ≤ −2+−4y

6x ≤ −4y −2

Step 2: Divide both sides by 6.

6x/6 ≤ $\frac{-4y-2}{6}$

x ≤ −2/3y + −1/3

Therefor, the answer is x≤ −2/3y + −1/3

* Hopefully this helps:) Mark me the brainliest:)!!

Find the area of a rectangle 3yds by 4/7yds

jasenka [17]

$\text{We're trying to find the area of the rectangle}\\\\\text{We know the dimensions are 3 by 4/7}\\\\\text{The formula to find the area of a rectangle is length x width}\\\\\text{Solve for area:}\\\\3\cdot\frac{4}{7}\\\\\text{Multiply the 3 to the numerator}\\\\\frac{12}{7}\\\\\text{Since we can't simply it, we'll leave it as is}\\\\\boxed{\text{Answer:} \frac{12}{7}\,\,yd^2}$
