i don’t know how to divide integers and i have a test tomorrow based on adding subtracting multiplication and division on intege
ryzh [129]

In order to divide integers, the first thing to check is the sign:

- When dividing two positive integers, the result will be a positive integer.

- When dividing two negative integers, the result will be a positive integer.

- When dividing integers with different signs (one negative and one positive), the result will be a negative integer.

Then, after checking the sign, we need to calculate the value of the division.

Some examples of divisions are:

\frac{24}{8},\frac{-15}{5},\frac{-100}{-10}

In the first division, the result is 3, because we have that 8 * 3 is equal 24.

Also, both numbers are positive, so the result is also a positive number.

In the second division, the result is -3, because 5 * (-3) is equal -15.

The result is negative, because the two numbers have different signs.

In the third division, the result is 10, because -10 * 10 is equal -100.

The result is positive, because both numbers are negative.

Sum of three numbers in an as is 33 and the sum of thier cubes is 5049.find the numbers
Alex73 [517]

Sum of three numbers is 33 and  sum of their cubes is 5049 then three numbers are 7,11,15 or 15,11,7.

As given,

Let a-d, a, a +d be three numbers

Sum =33

⇒a-d + a +a +d =33

⇒ a =11

Sum of cubes= 5049

⇒ (a-d)³ + a +(a +d)³ =5049

⇒ a³ -d³ -3a²d +3ad² + a³ +a³ +d³ +3a²d +3ad² =5049

⇒3a³ + 6ad² = 5049

⇒ d=± 4

Therefore, sum of three numbers is 33 and  sum of their cubes is 5049 then three numbers are 7,11,15 or 15,11,7.
