Seven less than one-half a number is 5.
how is that written as a equation.
If x is the number, then
(1/2)x - 7 = 5
0.5X-7=5
To write the given statement as an equation, you first need to define a variable for the unknown number. Let's use x to represent the number.
The word "less than" indicates that we need to subtract something from the number. Since it says "seven less than," we subtract 7 from the number.
The phrase "one-half a number" means (1/2)x. So, "seven less than one-half a number" can be written as (1/2)x - 7.
Finally, the statement says "is," which means it equals, so we can write the equation as:
(1/2)x - 7 = 5
This equation represents the statement "Seven less than one-half a number is 5."
