Answer:
The last option is the correct option. [tex]3-(n-1)=\frac{1}{2}(3n-4)[/tex]
Step-by-step explanation:
Given statement is: "three minus the difference of a number and one equals one-half of the difference of three times the same number and four”
If the number is [tex]n[/tex] , then "the difference of a number and one" means [tex](n-1)[/tex]
Now "three minus the difference of a number and one" means [tex]3-(n-1)[/tex]
"The difference of three times the same number and four" means [tex](3n-4)[/tex] and then "one-half of it" means [tex]\frac{1}{2}(3n-4)[/tex]
Thus, the expression will be: [tex]3-(n-1)=\frac{1}{2}(3n-4)[/tex]
Answer:
[tex]3-(n-1)=\frac{1}{2}(3n-4)[/tex]
Step-by-step explanation:
"three minus the difference of a number and one" this phrase can be written in mathematical form as, 3-(n-1)
and
"one-half of the difference of three times the same number and four" this phrase is written in mathematical form as [tex]3-(n-1)=\frac{1}{2}(3n-4)[/tex]
according to given statement when above both phrases equals then it is written as mention bellow;
[tex]3-(n-1)=\frac{1}{2}(3n-4)[/tex]
Hence the last provided expression is correct.
