The answer would be 10x+4y-13 which can also be written as 10x+4y=13.
28 trucks/7 hours=4 trucks/1 hour.
Therefore A.) and B.) are incorrect.
The wording of these last two answers confusesme but I believe the correct one is D.) because 1 hour (per-/) 4 trucks.
Hope this helps!

Answer:
Length of side AB = 5.6 cm
Step-by-step explanation:
From the figure attached.
In right triangle ABC,
m∠ABC = 62°
m(BC) = 12 cm
By applying Cosine rule in this triangle,
Cos62° = ![\frac{\text{Adjacent side}}{\text{Hypotenuse}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BAdjacent%20side%7D%7D%7B%5Ctext%7BHypotenuse%7D%7D)
Cos62°= ![\frac{AB}{BC}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BBC%7D)
0.46947 = ![\frac{AB}{12}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7B12%7D)
AB = 12 × 0.46947
AB = 5.63
≈ 5.6 cm
Therefore, length of side AB = 5.6 cm
