Which statement correctly describes what atoms and molecules are made of?

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

idk what the heck he answer is, i’m just putting this here so i finish my account

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

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
