write the expression for- the sum of twice the number X and 5
The Correct Answer and Explanation is:
The expression for the sum of twice the number XXX and 5 is: 2X+52X + 52X+5
Explanation:
When we say “twice the number XXX”, we mean multiplying XXX by 2, which gives 2X2X2X. “Sum” indicates that we need to add something to 2X2X2X. The phrase “and 5” means that we are adding 5 to the expression. Therefore, we combine these two components, and the final expression becomes 2X+52X + 52X+5.
- Twice the number XXX means 2X2X2X, since multiplying any number by 2 gives us “twice” that number.
- Sum of means that the next operation is addition.
- 5 is simply the number that will be added to 2X2X2X.
The expression 2X+52X + 52X+5 is a simple linear expression, where XXX represents any real number, and the sum gives us a new value depending on the value of XXX. For example, if X=3X = 3X=3, the expression becomes: 2(3)+5=6+5=112(3) + 5 = 6 + 5 = 112(3)+5=6+5=11
Thus, for any given value of XXX, you can plug it into the expression and compute the result. This type of expression is common in algebra for representing relationships between numbers, and it’s used in many areas such as equations, functions, and word problems.
