Emily is 4 ft 6 in and has a shadow that is 13 ft 6 in long. At the same time a tree cast a 120 ft shadow. How tall is the tree in ft?

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

i believe that the answer is

b. y-1=-2(x-4)

hope this !

i’m sorry but i don’t know sorry
