Joelle is working on a school report in a word processor. she wants to place a figure which is 13.09 cm wide so that it appears centered on the page. the width of the page is 21.59 cm. how much margin should she leave on the left so that the figure is centered?

its 4 because 2 times 2 is 4, if you double the number two you get four

i dont know

step-by-step explanation:

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
