In a two-digit number the units digit is three less than the tens digit. If the digits are reversed, the sum of the reversed num

makvit [3.9K]

Answer:

74.

Step-by-step explanation:

Let the number be xy.

Then from the given data

x = y + 3..........(1)

The numerical value of xy is 10x + y so the second equation is

10x + y + 10y + x = 121

11x + 11y = 121 Simplifying:

x + y = 11

x = -y + 11 .........(2) Adding equations (1) and (2):

2x = 14

x = 7

and therefore y = 7 - 3 = 4.

Barb walked 1.3 miles to her friend’s house and then 3/4 mile to the library. How far did Barb walk in all?

Marat540 [252]

Answer:

$2.05\ miles$ or $2\frac{1}{20}\ miles$

Step-by-step explanation:

we know that

To calculate the total distance Barb walked, add the distance to her friend's house plus the distance to the library.

$1.3+\frac{3}{4}$

Remember that

$1.3=\frac{13}{10}$

substitute

$\frac{13}{10}+\frac{3}{4}=\frac{13*2+5*3}{20}$

$=\frac{41}{20}\ miles$

$=2.05\ miles$

Convert to mixed number

$\frac{41}{20}=\frac{40}{20}+\frac{1}{20}=2\frac{1}{20}\ miles$
