Find the value of the variable and LN if M is between L and M <br><br> LM=4a,MN=8a,LM=40
Zanzabum

LN = 120 and a = 10

<u>Step-by-step explanation:</u>

If we need to find the variable a as, LN is the line and M is the mid point between L and N. So LN = LM + MN

LM = 4a = 40

a = \frac{40}{4} = 10

MN = 8a =  8×10 = 80

So LN = LM + MN

    LN = 40 + 80 = 120

Which number line shows the solution set for |p-3|=9?
Mademuasel [1]

Answer:

Option b

p = -6 or p = 12

Step-by-step explanation:

The absolute value is a function that transforms any value x into a positive number.

Therefore, for the function f(x) = |x|  x> 0 for all real numbers.

Then the equation:

|p-3| = 9 has two cases

(p-3) = 9    if h > 3  (i)

-(p-3) = 9    if h < 3 (ii)

We solve the case (i)

p = 9 + 3\\p = 12

We solve the case (ii)

-p +3 = 9\\p = 3-9\\p = -6

Then the solution is:

p = -6 or p = 12
