Answer:
it is 45
Step-by-step explanation:
677
When the last child has finished his or her schooling and is no longer dependent on the parents, the Echo stage begins. This is the pre-retirement or "empty nest" stage. For those individuals without children, the Echo stage begins about 10 years before retirement.
Divide the total by 3 to get the middle value:
294 /3 = 98
Now the 3 numbers are consecutive, so use the numbers on each side of 98:
Smallest = 97
middle = 98
Largest = 99
Answer:
347 and 865
Step-by-step explanation:
Let the two number be x and y
Therefore, from the given information:
x + y = 1212
x - y = 518
Rewrite both equations to make x the subject:
x = 1212 - y
x = 518 + y
Equate equations and solve for y:
1212 - y = 518 + y
694 = 2y
y = 347
Substitute found value of y into one of the equations and solve for x:
x = 518 + 347
x = 865
Therefore, the two numbers are 347 and 865
