The delivery person weights 160 lb and each box of books weights 40 lb. The maximum capacity of the elevator is 710 lb. How many
1 answer:
Answer:
The number of boxes = 13
Step-by-step explanation:
Given the weight of the delivery person =160 lb
The weight of each box of books=40 lb
maximum capacity of the elevator=710 lb
Let the max number of boxes of books be x. Now the total weight of the boxes and the delivery person should not exceed the maximum capacity of the elevator.
Therefore the maximum value of x is 13(since it is an integer).

Step-by-step explanation:
Assuming s and t are parallel
The two angles are same side interior angles and same side interior angles add to 180 when the lines are parallel
4x-12 + 120 = 180
4x -12 = 60
4x = 72
x = 18
That means 4x -12 = 4(18) -12 = 60
Vertical angles are equal. Alternate interior angles are equal. Alternate exterior angles are equal. All pink dot angles are equal.
Pink dots are 60 degrees
All blue lines are equal. They are 120 degrees
