n(1-R)L is an expression: it is not a formula.
Replace each variable in the expression by its value and then find the value of the expression.
As an expression it is: 5(p+r) which means 5p+5r
the sum of p and r is p + r5 times this sum is 5 × (p + r) = 5(p + r)Multiplication is not written as it looks like an 'x' - it is implied by two things next to each other.The brackets are needed as the addition needs to be done before the multiplication.

It means 'I have not actually done it but I am going to do it so soon that you can go ahead and act as if I have done it'. A rather meaningless phrase.
x = (r + st)/r is the expression that represents x in the equation rx - st = r.
It is a positive expression of something good,well done,a good surprise.
In algebra, "r" typically represents a variable or an unknown quantity. When you see "triple r" in an algebraic expression, it means that you are multiplying the variable "r" by three. So, "triple r" is equivalent to 3r in algebraic terms. This can be written as 3 * r or simply 3r, depending on the context of the expression.
-180
It is: r/15
If you mean: -12.75+4.25x then it is 4.25(-3+x)
35/r
35/r 35 ÷ r
r and s can be any values such that r + s = 39. The answer is indeterminate since there are many solutions for that expression. If the new expression is included, then there must be some r and s for the problem.
