Answer:

$m=\frac{p}{n-2}$

Step-by-step explanation:

$mn-p=2m$

move 2m to the left

$mn-p-2m=0$

move p to the right

$mn-2m=p$

factor out m

$m(n-2)=p$

divide by (n-2)

$m=\frac{p}{n-2}$

X<br> f(x) =<br> x2 + 4x<br> .<br> x2_4

PtichkaEL [24]

The answer is 1/(x+4)
Explanation:
You would factor out the denominator
So,
(X-4)(x+4)=x^2-16
So, x-4/(x+4)(x-4)
Then x-4 cancels each other out from the numerator and denominator
Leaving 1/x+4

Y-4x=3. 2x-3y=21 can someone help

mars1129 [50]

Y-4X =3 ; 2x-3y=21

Y= 3+ 4x

2x -3( 3+4x)= 21

2x- 9- 12x= 21

-10x -9= 21

-10x -9+9= 21+9

-10x = 30

X= 30/-10= -3

Y= 3+4x = 3+ 4* (-3)= 3-12= -9

Mrs. Duncan measured the lengths of a crayon and a pencil. The pencil is double the length of the crayon. The sum of their lengt

Margarita [4]

Answer: The length of pencil is 16 centimetres and length of crayons is 8 centimetres

Step-by-step explanation:

Let the length of crayon = $x$

Length of a pencil = $2x$

As according to question that the sum of their length is 24 centimetres

So we have

$x+2x=24\\\\\Rightarrow 3x= 24 \\\\\Rightarrow x= \dfrac{24}{3} =8$

Therefore the length of crayon = 8 centimetres

Length of pencil= $2x= 2\times x = 2\times 8 =16$ centimetres

Hence, the length of pencil is 16 centimetres and length of crayons is 8 centimetres
