4n-5
(Which is four times a number minus 5)
Let the number be x and so the expression is 4x -3
Oh, dude, it's like you're asking me to do math at a party. Okay, so "thrice a number" is just 3 times a number, and "five less than" means you subtract 5. So, the algebraic expression for "five less than thrice a number" would be 3x - 5. Easy peasy, right?
Generally speaking, a letter in algebra refers to a variable, that is, it is a placeholder for any specific value that can be used in that equation.In algebra syntax, a number next to a variable, or a variable next to another variable, with no explicit arithmetic symbol between them, mean to multiply the two values.So:2aMeans to multiply the variable value of "a" by two.In your question:2aball values should be multiplied. So, the result would be 2 times the variable value of "a" times the variable value of "b".
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.
-5 is the answer -20a divided by 4a is -5. If we times 4a by a positive number, we would get a positive number, so we have to times it by a negative number. The number can't have an a at the end as this would mean when we times it by 4a we would end up with a2 -5 x 4 = -20 then we add on the a = -20a
If x is used to represent the unknown number, then the expression for 20 times a number would be 20x.
In algebra, 2 times b would be written as 2b.
To write the expression "4 more than 6 times a number," you would start by writing the mathematical operation for "6 times a number," which is 6x. Then, you would add 4 to this result to get the final expression. Therefore, the expression can be written as 6x + 4.
This expression would be 3x-7.
5x^3
To write the sum of a number and thirty-seven in an algebraic expression, you would use the variable "n" to represent the number. The algebraic expression would be n + 37, where "n" represents the unknown number and 37 represents thirty-seven. This expression represents the sum of the unknown number and thirty-seven.

Let's say x is your "number" Remember, expressions do not have equal signs. If something in algebra has an equal sign, t is called an equation. (x/9) +5 would be your answer. Remember p.e.m.d.a.s. if asked to use that expression.
Assuming you call your number "n", the expression would be "14n". You can replace "n" with whatever variable you want to use.

x=unknown number So the expression would be: 4(x+3) The sum of a number (x) and 3, all multiplied by 4.
