(3x + 7)<br> (10x – 22)<br> What does x equal?

LenKa [72]

Answer:

3x+7=10x-22

We simplify the equation to the form, which is simple to understand

3x+7=10x-22

We move all terms containing x to the left and all other terms to the right.

+3x-10x=-22-7

We simplify left and right side of the equation.

-7x=-29

We divide both sides of the equation by -7 to get x.

x=4.14285714286

If the expression

yawa3891 [41]

Answer:

n = 1

Step-by-step explanation:

So the first step is to simplify the top equation:

(3v + 7) - (8v + 6)

distribute the negative sign to get rid of the second parentheses:

3v + 7 - 8v - 6

now, combine like terms

-5v + 1

Since it says it needs to be equivalent to (-5v + n), n is 1

**BRAINLIEST IF ANSWERED***

goblinko [34]

Answer:

(D)7 in.

Step-by-step explanation:

A regular hexagon can be divided into six equilateral triangles.

Therefore:

$b=\dfrac{c}{2}$

Applying Pythagoras Theorem

$c^2=12^2+b^2\\c^2=12^2+(\frac{c}{2})^2\\c^2-(\frac{c}{2})^2=12^2\\c^2-\dfrac{c^2}{4}=144\\\dfrac{4c^2-c^2}{4}=144\\\dfrac{3c^2}{4}=144\\$Cross multiply\\3c^2=144 \times 4\\3c^2=576\\$Divide both sides by 3\\c^2=192\\$Therefore:\\c=\sqrt{192}\\c=8\sqrt{3}$ in.$

Recall that b=c/2

Therefore:

$b=4\sqrt{3} \approx 7$ in.$

The value of b is 7 inches.
