There are a total of 127 cars on a lot if there are four more than twice the number of trucks than cars how any trucks and cars are on the lot
Answer:
t =12 m
Step-by-step explanation:
We can use similar triangles and proportions to solve this problem.
Put the smaller triangle on top and the larger triangle on bottom
12 9
------ = -------
16 t
Solve by using cross products
12 t = 9*16
12 t =144
Divide by 12
12t/12 = 144/12
t = 12
Assuming the frame is rectangular, the perimeter is 2*width + 2*length. so 5*2 + 2*length = 24. subtract ten from both sides to get the 14 = 2*length. the length = 7.
