M=p/n+4 make n the subject

Kipish [7]

Answer:

$n = \frac {p - 4m}{m}$

Step-by-step explanation:

Given the algebraic expression;

$m = \frac {p}{n + 4}$

To make n the subject of formula.

Cross-multiplying, we have;

$m*(n+4) = p$

$mn + 4m = p$

Rearranging the equation, we have;

$mn = p - 4m$

$n = \frac {p - 4m}{m}$

coldgirl [10]

Answer:

2.4 hours

Step-by-step explanation:

6 3/10 divided by 5 1/4 is 1.2. So 6 3/10 is 1.2 times more than 5 1/4. We then take the 1.2 and multiply it by 2 hours because we need to find what's 1.2 times more than 2 hours. So then you get 2.4 hours.

If (-2,4) are the coordinates of a point on the line whose equation is y=Mx+1 , what is the slope of the line?

horrorfan [7]

Slope of the line is -3/2

Step-by-step explanation:

Step 1: Given that (-2, 4) is a point on the line y = mx + 1, find slope m.

Since the point is on the line, the coordinates will satisfy the equation.

⇒ 4 = m × -2 + 1

⇒ 4 = -2m + 1

⇒ 3 = -2m

∴ m = -3/2
