Answer: Hence, Option (6) and (8) are correct as their value is also "-8".

Step-by-step explanation:

Since we have given that

\frac{2}{3}(6x+12)=-24

First we need to solve to get the value of 'x' :

\frac{2}{3}(6x+12)=-24\\\\6x+12=\frac{3}{2}\times (-24)\\\\6x+12=3\times (-12)\\\\6x+12=-36\\\\6x=-36-12\\\\6x=-48\\\\x=\frac{-48}{6}\\\\x=-8

Therefore, x=-8

Now, we will check all the options :

1) 4x+8=24

4x+8=24\\\\4x=24-8\\\\4x=16\\\\x=\frac{16}{4}=4

2) 9x+18=-24

9x+18=-24\\\\9x=-24-18\\\\9x=-42\\\\x=-4.67

3) 4x+12=-24

4x+12=-24\\\\4x=-24-12\\\\4x=-36\\\\x=\frac{-36}{4}=-9

4) 18x+36/2=-24

18x+18=-24\\\\18x=-24-18\\\\18x=-42\\\\x=-2.34

5) 4x=-36

x=\frac{-36}{4}=-9

6) 4x=-32

x=\frac{-32}{4}=-8

7) x=-9

8) x=-8

Hence, Option (6) and (8) are correct as their value is also "-8".

What's the approximate value of e?
VikaD [51]

Answer:

  (b)  2.71828 . . .

Step-by-step explanation:

If your calculator does not have an 'e' button, you can have it compute e^1 using the exponential function button.

__

  e ≈ 2.718281828459045...

__

Like pi, 'e' is a transcendental number, a number that is not the root of any polynomial with integer coefficients.

Kim sold christmas pies for 5.00$ each. She earned 156 how many pies she sold also let x repersent the number of pies, x, kim so
MA_775_DIABLO [31]

Answer: 31.2 pies

Step-by-step explanation:

Kim sold pies for $5.00 each and earned $156 from doing so.

The number of pies she sold to get to this was x pies.

The formula for doing so is therefore:

5 * x pies = 156

5x = 156

x = 156 / 5

= 31.2 pies

A chef has 10 spice jars, but his new spice rack only holds 8 spice jars.
miskamm [114]
This is a statistics problem on permutation and combination. To differentiate this, permutation involves on the arrangement in which order doesn't matter. For combination, order matters.

For example, if you arrange A, B and C, for permutation it could be AB, BA, CA, AC, BC and CB. But for combination, it would just be AB, AC and BC. 

So, in this problem where he is asked to arrange 8 jars in which order doesn't matter. It is permutation. You can solve this just by calculator. The formula would be nPr, where n is the total number of items while r is the number of items to be sorted. Thus,

nPr = 10P8 = 1, 814,400

Thus, the answer is B.
