Question

the product of three integers is - 600. If two of them are - 15 and 10, find the third integer

Answer 1

-15 * 100 * x = -600
x = -600
____

-150
x = 4
thus the number is 4

Answer 2

Concept:

The rules for multiplying two integer numbers:

The outcome is positive if both integers have the same sign.

If the signs of the numbers mismatch, the outcome is negative.

Given:

Product of three integers= -600

Two integers are -15 and 10

Find:

The third integer

Solution:

Let the third integer be $x$.

Product of three integers= -600

Therefore,

$x* (-15) * 10 = (-600)$

$x * (-150) = (-600)$

$x= (\frac{600}{150})$

$x = 4$

The third integer is 4.
