$n = 10$

Step-by-step explanation:

Required

Find m and n

Considering the given angle, we have:

$\sin(60) = \frac{Opposite}{Hypotenuse}$

This gives:

$\sin(60) = \frac{m}{20}$

Make m ths subject

$m = 20 * \sin(60)$

$\sin(60) =\frac{\sqrt 3}{2}$

So, we have:

$m = 20 *\frac{\sqrt 3}{2}$

$m = 10\sqrt 3$

Considering the given angle again, we have:

$\cos(60) = \frac{Adjacent}{Hypotenuse}$

This gives:

$\cos(60) = \frac{n}{20}$

Make n the subject

$n = 20 * \cos(60)$

$\sin(60) =\frac{1}{2}$

So, we have:

$n = 20 *\frac{1}{2}$

$n = 10$

Substitution for:<br> X-5y=10<br> 2x-10y=20

sergey [27]

Since you need an isolated variable to use the substitution method, we need to re-arrange one of the equations. This will probably be easiest to do with the first one.
Add 5y to both sides of the first equation.
x=10+5y
Now, in the second equation, put in 10+5y in any spot that has an x.
2(10+5y)-10y=20
Distribute the 2 to both numbers in the parenthesis.
20+10y-10y=20
Combine like terms.
20=20
This means that the two equations are actually the same. You can see this if you multiply the whole first equation by 2
2(x-5y=10)
2x-10y=20, which is the same as the second equation. Therefore, the two equations are actually the same one.

Solve the equations<br>Y=2x-4, 3x+y=1

liberstina [14]

Step-by-step explanation:

$y = 2x - 4$

$3x + y = 1$

$y = 1 - 3x$

Equating,

$2x - 4 = 1 - 3x$

$2x + 3x = 1 + 4$

$5x = 5$

$x = 1$

Placing it,

$y = 1 - 3( 1)$

$y = 1 - 3$

$y = - 2$

What is 4 times 31 in distributive property

Aleksandr [31]

Answer:

4(30 +1)= 4(30) + 4(1)

Step-by-step explanation:

The property states a(b+c)= ab+ac.

30 and 1 equals 31, then you just plug the two numbers into the equation.
