Say the number was 4, you plus it by 5 so it is 9, times it by 8 and you got 72. for the 'and a number' you would have to be more specific
Drink coke not pepsi
It is: 80
5+(8*X) = Y You don't have enough info. to solve for Y.... I think. :)
-1
5
Think of x as a number lets say that x is 5 so 8+5=13 5+8=13 however 5-8= -3 because i am taking away -8 from 5 8-5= 3 because i am taking away 5 from 8 in subtraction you need to be aware of the minus sign and what number to in front of it.
It is: 80

The sum of 8 and 5 is 13. There is then no number with which to calculate its product.
8n +3
It is: -5+1+8+5 = 9
5+(8*X) = Y You don't have enough info. to solve for Y.... I think. :)
8x + 5
-1
5x - 8
8 and 3
5
8/5 + 2/5 = 10/5 = 2 which is an integer: not a mixed number.
