We know that
To find the LCM<span>,
we must find the prime factorization of each number
</span>15=3*5
8=2³
Now, we have to multiply the different<span> factors, and we only choose the ones which have the greatest exponent.
</span>LCM=3*5*2³-----> LCM=120

the answer is
LCM is 120

I need help...............
Viefleur [7K]

Answer:

$7

Step-by-step explanation:

You can see that it "rises" 700 and "runs" 100, that means that there is a slope of 700/100. If you simplify that, it turn out to be a slope of 7. Meaning that each ticket costs $7. Hope this helps, let me know if you need a better explanation!

Solve the inequality -8x - 10 &gt; 7x + 20.<br> OX-30<br> Ox&gt;-2<br> Ox&gt;-30<br> 0x&lt;-2
galina1969 [7]

Answer:

<h2>x < - 2</h2>

Step-by-step explanation:

-8x - 10 > 7x + 20

First subtract 7x from both sides of the inequality

That's

- 8x - 7x - 10 > 7x - 7x + 20 \\  - 15x  - 10 > 20

<u>Add 10 to both sides of the inequality</u>

- 15x + 1 0 - 10 > 20 + 10 \\  - 15x > 30

<u>Divide both sides by - 15</u>

\frac{ - 15x}{ - 15}  >  -  \frac{30}{15}

Since the denominator is negative the sign will change

We have the final answer as

<h3>x < - 2</h3>

Hope this helps you
