The length of the longest side of a triangle is 1 inch less than the sum of the lengths of the other two sides. How long is the longest side of this triangle if the perimeter is 35 inches?

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

83-45=38

38 was the other number

hope your goes well, here's a turkey
