Answer:

3 inches

Step-by-step explanation:

If the dog chews off 4 inches every day, you first have to multiply the inches by the number of days, which in this case is 3 x 4, which equals 12. In 3 days, he chewed off 12 of the original 15 inches, leaving only 3 inches left.

In a two-digit number, the tens digit is 5 less than the units digit. The number itself is five more than three times the sum of
Luden [163]

Given:

In a two-digit number, the tens digit is 5 less than the units digit.

The number itself is five more than three times the sum of its digits.

To find:

The number.

Solution:

Let the two digit number is ab. So,

ab=10a+b

Tens digit is 5 less than the units digit.

a=b-5       ...(i)

The number itself is five more than three times the sum of its digits.

10a+b=3(a+b)+5

10a+b=3a+3b+5

10a+b-3a-3b=5

7a-2b=5          ...(ii)

Using (i) and (ii), we get

7(b-5)-2b=5

7b-35-2b=5

5b=5+35

5b=40

b=8

Putting b=8 in (i), we get

a=8-5

a=3

Therefore, the required number is 38.
