Blizzard [7]3 years ago
8 0

Answer:

  75

Step-by-step explanation:

Let t and u represent the tens and units digits, respectively.

  t = u + 2 . . . . the tens digit exceeds the units digit by 2

  t + 2u = 17 . . . . the sum of the tens digit and twice the units digit is 17

Substituting for t in the second equation, we get ...

  (u +2) +2u = 17

  3u = 15 . . . . . . . . subtract 2

  u = 5 . . . . . . . . . . divide by 3

  t = u+2 = 7

The number is 75.

7 exceeds 5 by 2. 7 + twice 5 = 7 + 10 = 17.

katen-ka-za [31]

Answer:

Step-by-step explanation:

To simplify this expression, you will need to use the distributive property.

Multiply -2/5 by 15 = <u>- 6</u>, -2/5 by -20d = <u>8d</u>, and -2/5 by 5c = <u>-2c</u>.

you can switch these around to get -6 + 8d - 2c and -2c + 8d - 6.

Hope this helps :)
