5
If you call your number x, the expression would be 5x.
The property you are referring to is the Distributive Property. It states that when you multiply a number outside parentheses by each term inside the parentheses, you distribute the multiplication across all terms. For example, in the expression ( a(b + c) ), you would multiply ( a ) by both ( b ) and ( c ), resulting in ( ab + ac ).
That would be the number 1.
If you call the number "n", then the expression would be "n+5".
an even number.
An number with a x after mean multiply, so it would be 4x12=48
8z + 5
If you call your number x, the expression would be 5x.
To express "7 times a number increased by 4" mathematically, you would write it as 7x + 4, where x represents the unknown number. This expression indicates that you multiply the number by 7 and then add 4 to the result. So, if the number is 5, the expression would be 7(5) + 4 = 35 + 4 = 39.
That would be the number 1.
If x is used to represent the unknown number, then the expression for 20 times a number would be 20x.
If you call the number "n", then the expression would be "n+5".
an even number.
Let the number be x and so the expression would be: x+20
To express "16 more than twice a number" in mathematical terms, you would write it as 2x + 16, where x represents the unknown number. This expression indicates that you first multiply the number by 2 (twice the number) and then add 16 to the result.
you would get an even number!
Since the prefix "kilo" means thousand, you multiply by 1000.
