Hello there >3 i would like explanation for this :)
Blizzard [7]

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.

_____

<em>Check</em>

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

max2010maxim [7]

Answer: The system of equations that could be used to determine the number of small cups sold and the number of large cups sold is

6x + 18y = 780

y = 4x

Step-by-step explanation:

Let x represent the number of small cups that were sold.

Let y represent the number of large cups that were sold.

Each small cup holds 6 ounces of lemonade and each large cup hold 18 ounces of lemonade. Lincoln used 780 ounces. This is expressed as

6x + 18y = 780- - - - - - - - - - 1

Lincoln sold 4 times as many large cups as small cups. This is expressed as

y = 4x
