The sum of five and a number n is at least 12

Step-by-step explanation:

If you simply need to identify the inequality, it is

n + 5 ≥ 12

since "sum" means to add and "at least" is the inequality sign that is greater than or equal to.

If you are solving it, then the solution set will be

n ≥ 7

5 + n ≥ 12.

Step-by-step explanation:

Given  :  sum of five and a number n is at least 12.

To find : Write expression .

Solution : We have given sum of five and a number n is at least 12.

According to given statement :

Sum of 5 and n

5 + n

At least 12 mean the number is 12 or greater than 12

So ,

5 + n ≥ 12.

Therefore, 5 + n ≥ 12.

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
