Answer:
So, the initial number of apples is 7.
Step-by-step explanation:
The number of apples of An, Binh, and Chi are the same. An gave away 17 apples, Chi gave away 19 apples, so now Chi's apples are 5 times higher than the total remaining apples of An and Binh. How many apples did each of you have at first? (Solve the above problem by equation or system of equations)
Let the initial numbers of apples is a.
An gave 17 apples
Chi gave 19 apples
So,
x - 19 = 5 (x - 17 + x)
x - 19 = 5 (2x - 17)
x - 19 = 10 x - 85
9 x = 66
x = 7
Answer:
The flagpole is 15 feet tall.
Step-by-step explanation:
The man casts a shadow that is 2/3 the length of his height. Because we know that the man and the flagpole are standing at the same time of the day, we can conclude that the shadow of the flagpole is 2/3 the length of the flagpole as well. Then, you would multiple 10(3/2) to get 15 as the height of the flagpole.
