4n-5
(Which is four times a number minus 5)
Let the number be x and so the expression is 4x -3
-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
An algebraic expression is a term used in algebra, describing an expression containing one or more numbers, variables, and arithmetic operations. An example sentence would be: They all agreed to algebraic expression seemed impossible.
an example of an algebra equation would be: 1/3(15+6a)4 read out loud would be: one-third times the quantity of 15 plus six A times 4. this is a basic algebra problem. very easy
That would mean d times 2.
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.
This expression would be 3x-7.
5x^3
Let the number be x and so the expression is 4x -3
Assuming you call your number "n", the expression would be "14n". You can replace "n" with whatever variable you want to use.
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.
x=unknown number So the expression would be: 4(x+3) The sum of a number (x) and 3, all multiplied by 4.
I believe it would be 3-5x (x being the number multiplied by 5)
I would say the anwser would be 11
If a certain number of hours is "x", then 8 times as much would simply be "8x".
twenty four times a number and add 19
