1 inch of the model - 18 inches of the car
9 inches of the model - x inches of the car

The car is 162 inches long.
-10, I believe that is the answer.
Answer:
98
Step-by-step explanation:
From the statement of similarity, we can write this proportion.
TV/MV = UV/LV
28/x = 16/56
16x = 28 × 56
x = 7 × 14
x = 98
23 = (2a) + 6
23- 6 = 2a
17 = 2a
17/2 = 2a/2
a = 8.5
