tiny-mole [99]

Complete question :

The sugar maple tree in Joshua's yard is 1/4 the age of the oak tree in his yard. The sugar maple tree is 20 years old. How old is the oak tree?

Answer:

80 years

Step-by-step explanation:

Given that :

Sugar maple tree = 1/4 age of oak tree

Age of sugar maple tree = 20

Age of oak tree = x

20 = 1/4 * x

20 = x / 4

Multiply both sides by 4

20 * 4 = (x / 4) * 4

80 = x

Hence, Age of oak tree = 80 years

Show that any number of the form ABCABC (e.g. 356356) is divisible by 13.
Shtirlitz [24]

We could write such a number as

10^5a+10^4b+10^3c+10^2a+10b+c

=10^2(10^3+1)a+10(10^3+1)b+(10^3+1)c

=(10^3+1)(100a+10b+c)

10^3+1=1001=13\cdot77 so we're done.
