Answer:
x = 5
Step-by-step explanation:
Given that,
NL = 5x, LM = 3x, and NL = 15
L is between M and N.
To find,
The value of x.
Solution,
It is mentioned that, L is between M and N. So,
LM = LN
Put all the values,
3x = 15
⇒ x = 5
So, the value of x is equal to 5.

To find the incompleted portion of the test, convert the decimal to a percentage by moving the decimal two places to the right. .7 as a percentage is 70%. subtract 70% from 100%, giving you 30%. Juan has not completed 30% of his test, or 5 questions.
Answer is in The picture attached. Hope it helps!
Solve for m:
(-3 m)/7 = 12
Multiply both sides of (-3 m)/7 = 12 by -7/3:
(-7 (-3) m)/(3×7) = (-7)/3×12
(-7)/3×(-3)/7 = (-7 (-3))/(3×7):
(-7 (-3))/(3×7) m = (-7)/3×12
(-7)/3×12 = (-7×12)/3:
(-7 (-3) m)/(3×7) = (-7×12)/3
(-7)/7 = (7 (-1))/7 = -1:
(-3-1 m)/3 = (-7×12)/3
(-3)/3 = (3 (-1))/3 = -1:
--1 m = (-7×12)/3
(-1)^2 = 1:
m = (-7×12)/3
12/3 = (3×4)/3 = 4:
m = -74
-7×4 = -28:
Answer: m = -28
