<u><em>Question</em></u>
<em>If the CP of 15 articles equals to the SP of 12 articles, find the gain percent.</em>
<em></em>
Answer:
gain percent = 25%
Step-by-step explanation:
To solve the question given, we will follow the steps below:
gain% =
× 100%
But from the question;
"CP of 15 articles equals to the SP of 12 articles", this implies that
15 c.p = 12 s.p
s.p = 15c.p / 12
s.p =
= 
s.p = 
substitute s.p =
into the formula
gain% =
× 100%
=
× 100%
=
× 100%
=
÷ c.p × 100%
=
×
× 100%
=
× 100%
= 25 %
Estimating Sums of Single Digit Numbers
Which of the following represents the most accurate estimation of 4 + 8? is the answer 5, 10, 20 or 25
The line has equation

where
is any real number.
is the line containing all scalar multiples of the vector (-1, 4, -3); we add (4, -4, 8) to shift the line so that it passes through this point while remaining parallel to the the line.
To get the symmetric form, we have

Solving for

Answer:
C
Step-by-step explanation:
4x + 3 = x + 3x + 5
4x + 3 = 4x + 5 //-4x on both sides
3 = 5 //Since the statement is false, it's no solution.
If, it had 3 = 3 or any number n = n, the solution would be infinite. But, if x is equal to any number n, x=n, it would have only one solution.
