The algebraic expression for: the sum of a number and 5 decreased by twice the number is (n + 5) - 2n
<h3>Algebra</h3>
let
sum of a number and 5
= n + 5
decreased by twice the number
= -2(n)
= - 2n
sum of a number and 5 decreased by twice the number
= (n + 5) - 2n
= n + 5 - 2n
= 5 - n
Therefore, the algebraic expression which can be used to represent; the sum of a number and 5 decreased by twice the number is (n + 5) - 2n

15 pencils were left from the box of pencils Amaiya bought.
Step-by-step explanation:
Number of pencils in box = 36
Ratio of used pencils to not used = 7:5
Let,
7x be the total pencils used.
5x be the total pencils not used.
Therefore,
7x+5x=36
Dividing both sides by 12;
Therefore,
Used pencils = 7x = 7*3 = 21
Not used pencils = 5x = 5*3 = 15
15 pencils were left from the box of pencils Amaiya bought.
