Describe the error in determining the value of X that makes the triangles congruent. Then, What is the correct value of x that makes the triangles congruent

Third option is correct.

correct value of x is 2.

where are the choices?

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
