Answer:

It is clear that the multiplication of two values in Eq A is done to get the LCM while same method is not applied for eq B .

Step-by-step explanation:

Given as :

The two statement are

A) The LCM of 5 , 13 = 65

Here The multiple of 5 = 1 × 5

And The multiple of 13 =  1 × 13

So, Applying prime factor method,

least common multiple = product of height power of all factors that occur in resolution

So, LCM = 1 × 5 × 1 × 13

i.e LCM = 65

<u>Again</u>

B) The LCM of 6 , 8 = 24

Here The multiple of 6 = 1 × 2 × 3

And The multiple of 8 =  1 × 2 × 2 × 2

i.e  The multiple of 8 =  1 × 2³

So, Applying prime factor method,

least common multiple = product of height power of all factors that occur in resolution

So, LCM = 2³ × 3

i.e LCM = 24

Hence, It is clear that the multiplication of two values in Eq A is done to get the LCM while same method is not applied for eq B . Answer

If x = 2.7, 5x = ____. (Input decimals only, such as 12.7.)
lukranit [14]

Answer:

5x=13.5

Step-by-step explanation:

Well, we know that 1x=2.7. So, if we want 5x we need to multiply 2.7*5 becuase 1x=2.7, so 5x=2.7*5.

Multiply. 2.7*5=13.5

So, 5x=13.5.

Hope this helps!

Answer:

(-6, -5)

Step-by-step explanation:

If you go left 9 times from 2, it goes to -6. Ex: 2, 1, 0, -1, -2, -3, -4, -5, -6. The same goes for 3 units up from -8.

Which value of x is in the solution set of -3X+8≥14? ) A. -3 B. -1 C. 0 D. 3 ​
romanna [79]

Answer:

A

Step-by-step explanation:

Solving for x:

-3x + 8 ≥ 14

-3x ≥ 6

x ≤ -2

Notice the sign gets reversed when you divide or multiply by a negative number.

The only option less than -2 is -3, A.

Here's a tip: on multiple choice questions, sometimes it's faster to try each answer instead of solving the equation.  This can save time on tests like the SAT or ACT.

Let's try it:

-3(-3) + 8 = 9 + 8 = 17

-3(-1) + 8 = 3 + 8 = 11

-3(0) + 8 = 0 + 8 = 8

-3(3) + 8 = -9 + 8 = -1

So you can see the answer is A.
