Wilma is thinking of a number that is divisible by both 17 and 8. What is the

svet-max [94.6K]

Answer: The smallest possible number is 136.

Step-by-step explanation:

1. You need to find the Least common multiple (LCM), which is the smallest of the common multiples of 17 and 8.

2. You can descompose 17 and 8 into primes factors. Then, you obtain:

$17=17$

$8=(2)(2)(2)=2^{3}$

3. Now, you must choose commons and no commons with the greatest exponent and multiply them. Therefore the result is:

$(17)(2^{3})=136$

$LCM=136$

2x+4≥24<br> solve for x<br> plz help me!

Margarita [4]

In order to solve for x, we must isolate it on one side of the inequality.

2x + 4 ≥ 24

The first step we will take is subtract 4 from both sides, since it is being added on the side with the variable.

<span>2x + 4 ≥ 24
</span> - 4 - 4

And the inequality now is

2x ≥ 20

Now, all we have to do is divide both sides by 2, since the variable is being multiplied by 2.

2x ≥ 20
/2 /2

And the final inequality is

x <span>≥ 10
Hope that helped! =)</span>
