What is additive property

Answer and Explanation:

I'm assuming you mean the "Additive property of equality".

The additive property of equality states if the same value amount is added to both sides of an expression or equation, it will remain equal.

Similarly, the additive property of  inequalities states if the same value amount is added to both sides of an inequality, it will remain true.

step-by-step explanation:

sorry i just needed points for a quiz plz for give me

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
