A coefficient is a number that is attached to a term.
For example:
3x² - 5x + 6 = 0
The coefficient of x² is 3.
The coefficient of x = -5.

Answer:
The expression (2 x 3) + 13 - 1 on simplifying gives 18.
Step-by-step explanation:
Here, the outcome of the expression is 18.
Using at least three operations.
Here, we use three operations Addition = '+' , Subtraction = '-' and
Multiplication = 'X'
Take the number 2 and multiply it with other number 3.
We get 2 x 3 = 6
Take the product, add it with another number 13
So, 6+ 13= 19
Take the resultant and subtract 1 from it.
We get 19 - 1 = 18
⇒The combined expression is (2 x 3) + 13 - 1 = 18
The above expression on simplifying gives 18.
I don't want to give you the answer so here is a thorough explanation and an answer if you want it. Set this up as a proportion. Set it up as 5/5=x/12.5. Then multiply 5 by x to get 5x and 12.5 by 5. Once you have this answer, divide it by five to isolate the x. Once you have finished this, you have your answer.
I got the answer 12.5. Make sure you check this so you understand how to solve these kinds of problems.
