let the no. be 'x'
therefore, the expression of 5 less than a no. is,
x-5
5
Subtract 25 from whatever variable you use for "a number". If your number is "x", then the expression becomes "x - 25".
t-9
Yes, an expression can have more than one variable.
It is x/3 - 8
Which symbols are you referring to? Can you give specific examples? All letters (absdefg...) are variables which are used to represent an unknown number. The variables are like placeholders; the number exists, you just don't know what it is yet. > is the "Greater than" sign, which means the number/variable/expression on the left is "grater than" the number/variable/expression on the right. < is the "Less than" sign. See above. = is the "Equals" sign, which means the sides are equal.
x-2
Subtract 25 from whatever variable you use for "a number". If your number is "x", then the expression becomes "x - 25".
In this case, you'll have to use a variable. Variables are basically a symbol which stands for a number. Let's use the variable "m". You're searching for 58 less than a number. That is basically just "word form" for a number, or a variable, minus 58. So if we use the variable "m", the expression will be m-58. Remember that you can use any variable you want.
Your variable (a number) X, minus 100. X - 100
The expression can be thus: 3x-3 whereas x is the unknown variable
It is: p-2
Subject: Algebra Topic: Expression Evaluation Step 1: Let the number be represented by the variable ( x ). Step 2: Write the expression for "a square of a number": ( x^2 ). Step 3: Write the expression for "3 less than a square of a number": ( x^2 - 3 ). Step 4: Provide the final answer: The expression representing "3 less than a square of a number" is ( x^2 - 3 ). Explanation: The expression ( x^2 - 3 ) represents the result of subtracting 3 from the square of a given number ( x ).
7 less than k
z - 7
5 less than y
