Let t be the amount of trucks.
Thus 5t is the amount of cars.
t + 5t = 30
6t = 30
t = 30/6
t = 5
Therefore, there are 5 trucks
X = 1/cos(30)
X = 1.154700538
X = 1.2 (nearest tenth)
2 more because 5 is 5-3 = 2 so the answer is 5/2
Step-by-step explanation:
[(-3 × 2 × (-4)] ÷ [-6 × 12]
[3 × 2 × -4] ÷ [-6 × 12]
[6 × -4]/[-6 × 12]
-4/(-1 × 12]
-4/-12
⅓
Option A is wrong
Option B is wrong -9/-18 = ½ not ⅓
Option C is correct = -24/-72 = ⅓
Option D is wrong = 9/-18 = -½ not ⅓
