A plane flew from its home base to an airport 225 miles away. With a head wind, the trip took 1.7 hours. With a tail wind the trip took 1.5 hours. Find the average wind speed and the average airspeed

answer:   c ?

step-by-step explanation:

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

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

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
