Five greater than an unknown number can be expressed as ( x + 5 ), where ( x ) represents the unknown number. This means if you were to take the unknown number and add five to it, you would arrive at the result.
The product of five and the sum of a number and six can be expressed mathematically as ( 5 \times (x + 6) ), where ( x ) represents the number. This means you first add the number ( x ) to six and then multiply the result by five.
My number is 11.
Three Working backwards from 11 then add 4 to make 15 then dividing 15 by 5 makes 3

Just add all the numbers, then divide by the size of the set. For example, if you have a set of five numbers, add all of them, then divide the result by five.

Add up the number of weights (:
No. When you add a positive and negative number, the bigger one determines the sign of the result. For example, when you add -5 and 3, the result will be negative because the negative number is larger. When you add -4 and 6, the result will be positive because the positive number is larger.

1.25 Let a be the unknown number then :- a + 5 = 5a 5 = 4a a = 5/4 = 1.25 Check : 1.25 + 5 = 6.25 : 1.25 x 5 = 6.25
It is 3*(q + p)/(r + s)
