3 0

Answer:

There is only one solution. x = 2

Step-by-step explanation:

3(x + 2) = 14 - x

3x + 6 = 14 - x

3x + x = 14 - 6

4x = 8

x = 2

If an integer n has three unique prime divisors, then it follows that the largest prime divisor of n is less than or equal to cu

TiliK225 [7]

Answer:

False

Step-by-step explanation:

Lets call the three prime divisors of n p, q, and r, being r the largest, we know:

$n=q * p * r$

Now, if

$q * p < r$

then

$n < r * r = r^2$

So:

$\sqrt{n} < \sqrt{r^2} = r$

Also, for every natural greater than one, we know:

$\sqrt[3]{n}$

from which:

$\sqrt[3]{n} < r$

So, we see, this means the preposition is false, we can find a particular counterexample:

q=2

p=3

p*q = 6

We need to choose a prime greater than 6

r=7

n= 2 * 3 *7 = 42

$\sqrt[3]{42} = 3.4760 < 7$

Answer:

-569

Step-by-step explanation:

$20 - 30 + (40)(11) - 12 + 13 - 1000$
$-10 + (40)(11) - 12 + 13 -1000$
$-10 + 440 - 12 + 13 -1000$
$430 - 12 + 13 - 1000$
$418 + 13 - 1000$
$431 - 1000$

True or false: 4/8 and 10/16 are equivalent fractions?

lorasvet [3.4K]

Answer:

False

Step-by-step explanation:

Multiply 8 by 2 to create the common denominator (which is 16).

Now multiply 4 by 2 to keep the fraction even.

This gives you the fraction 8/16 which is not equivalent to 10/16.

Another way you could write this inequality:

8/16 < 10/16
