Required
Determine the number of truckloads ordered
The question is incomplete as the total number of trucks were not given.
Assume the number of trucks is x.
The ordered truckloads would be:

Assume x is 100


$$ 12 - 5[(4 + 2)\div\2 - (22 + 10)]= 157 $$

Answer:
The answer to your question is 43.8 mL of acid.
Step-by-step explanation:
Data
Total volume = 362 ml
12.1 % is acid
The Volume of acid = ?
Process
1.- Use the rule of three and cross multiplication to solve this problem.
362 ml ------------------- 100%
x ------------------- 12.1 %
x = (12.1 x 362) / 100
x = 4380.2 / 100
x = 43.802 ml
2.- Round your answer to the nearest tenth.
43.802 only consider the first decimal
43.8 mL
3.- Conclusion
A 12.1% solution of acid has 43.8 mL of acid.
Answer:

Step-by-step explanation:
1. Value of x
The diagonals of a rectangle are equal, so
PR = QS

2. Length of each diagonal
PR = 11x - 20 = 11×18 - 20 = 198 - 20 = 178
QS = x + 160 = 18 + 160 = 178
The length of each diagonal is 178.
