X=2

Step by step explanation
10-2x=3x
Subtract 10 from both sides
-2x=3x-10
Subtract 3x from both sides
-5x=-10
Divide both sides by 2

Solve the formula for the specified variable N=(1/6)rm what is r

4vir4ik [10]

N=(1/6)rm

Solve for r

$N = \frac{1}{6} rm$

$N = \frac{1}{6}*r*m$

To remove the fraction 1/6, we multiply both side by reciprocal 6/1

$N\frac{6}{1}= \frac{1}{6}*r*m\frac{6}{1}$

6N = rm

Now divide by m on both sides

$\frac{6N}{m}= \frac{r}{m}$

$\frac{6N}{m}= r$

We solved for r

$r = \frac{6N}{m}$

Triangles PQR and FGH are similar. Also, What is the ratio of the area of triangle PQR to the area of triangle FGH?

svlad2 [7]

Theorem : If two similar triangles have a scale factor of a : b, then the ratio of their areas is a^2 : b^2.
We have a: b = 1: 1; then a^2 : b^2 = 1^2 : 1^2 = 1;

How many solutions does this system have? x + 2y = -1 2x + 4y = -2

gladu [14]

Answer:

Infinitely many solutions.

Step-by-step explanation:

x+2y=-1

2x+4y=-2

-----------------

x=-1-2y

2(-1-2y)+4y=-2

-2-4y+4y=-2

-2+0=-2

-2=-2

infinitely many solutions
