1 answer:

6 0

For an example when you need to regroup like for example
15

_____
You will see 9+ 5 = 14 so you will need to regroup the one into the 1 and leave the 4 below the 5 and 9

I might not be answering your question though, because I need to know what equation is it

Kitty [74]

Answer:

x = 12

Step-by-step explanation:

"Using the variable x for unknown number what is five more than the quotient of a number and 6 equals 7" translates into 5 + x/6 = 7.

To solve use inverse operations.

$5 + \frac{x}{6} = 7\\\\\frac{x}{6} = 2 \\\\ x = 12$

Which Product will result in a cell or difference of cubes?<br> Pls do not give any joke answers

Rom4ik [11]

Answer:

(x-9)(x²+9x+81); it'll give a difference of cubes

Step-by-step explanation:

Generally, the difference of cubes formula is (a³-b³)=(a-b)(a²+ab+b²), and the third option is the only one which fits it; with "a"= x and "b"= 9.

*The sum of cubes formula is (a³+b³)=(a+b)(a²-ab+b²); for future reference.

How many 4 digit numbers are there with the sum of the four digits equal to 34

Masteriza [31]

Answer:

Step-by-step explanation:

THE LARGEST 4 DIGIT NUMBER IS 9999 WHICH HAS SUM OF DIGITS 9+9+9+9 =36 SO TO HAVE A SUM OF DIGITS 34 ,WE HAVE TO TAKE 2 AWAY THERE ARE TWO WAYS TO DO THAT IS

1) TAKE 2 AWAY FROM 1 OF THE 9"S AND THE SET OF THE DIGITS (7,9,9,9)

2)TAKE 1 AWAY FROM 2 OF THE 9"S AND THE SET OF DIGITS (8,8,9,9)

THERE ARE 4 ARRANGEMENTS OF THE DIGITS (7,9,9,9) BECAUSE THERE ARE FOUR POSITIONS FOR THE DIGITS THOUSANDS,HUNDREDES,TENS AND UNITS SO WE CAN PICK A P[OSITION FOR THE 7 IN (4,1) = FOUR WAYS ( THERE ARE 7,9,9,9, 9,7,9,9, 9,9,7,9, 9,9,9,7

THERE ARE SIX ARRANGEMENTS OF THE DIGITS (8,8,9,9, BECAUSE THERE ARE FOUR POSITIONF FOR THE DIGITS THOUSANDS , HUNDRED , TENS AND UNITS SO WE CAN PICK A POSITIONS FOR THE 28"S IN (4,2) = 6 WAYS THEY ARE 8,8,9,9, 8,9,8,9, 8,9,9,8, SO THAT 4+6 OR 10 WAYS
