a number has 8 tens and same number of ones tens. what is the number?
Answer:
Let's denote the number of tens as x. The statement says that a number has 8 tens and the
same number of ones. In the decimal system, when you have a number like xy, it means x
tens and y ones.
So, in this case, the number has z tens and zx ones. The number can be represented as
102 + 2.
The given information is that « = 8. Substitute this value into the expression:
10x + x = 10(8) +8
=80+8
= 88
So, the number is 88.
