The tens digit is three less than the units digit. If the digits are reversed, the sum of the reversed number and the original number is 121. Find the original number. help

47, 74

Step-by-step explanation:

Let x = units digit

x – 3 = tens digit

Then the number is 10(x – 3) + x and the reversed number is 10(x) + (x – 3)

Equation

The reversed number plus the original number equal 121.

10(x) + (x – 3) + 10(x – 3) + x = 154

10x + x – 3 + 10x -30 + x = 121

22x – 33 = 121

22x = 154

x = 7 (units digit)

x – 3 = 4 (tens digit)

Answer

The number is (4 X 10) +7 or 47.

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
