Answer: Her estimate is incorrect because she has to have 25 trucks to be able to ship all her boxes.
Step-by-step explanation: Divide 539 by 22 and if there is a remainder then you need to have one more because you cant take half a truck.
539/22=24.5. Since there is a remainder, you will need 25 trucks total

Answer: 6
Step-by-step explanation:
Simplify the expression.
58 inches. 4 feet is equal to 48 inches and if the rock is sinking at -2 feet an second for 5 seconds, then that is -10 inches and the absolute value of -10 is 10 so 10+48=58
