30. 

3/4 is equal to 75%, so take 75% of 40 by multiplying .75 by 40 to get 30

The answer is 30.. because you divide 40 by 4, which is 10 then you multiply by 3 which is 30..

What is 18 divided by 0.2 and how?
kati45 [8]
0.2 is the same as 2/10

18/(2/10)

As you may have learned in school, when you divide a fraction, you flip the fraction in the denominator, and change it to multiplication

18/(2/10) becomes 18 x (10/2)

multiply normally

18 x 10 = 180

divide to find answer

180/2 = 90

90 is your answer

hope this helps

Remember, when you meet this problem, flip the second fraction, and change the division sign into multiplication. (always second, never first (if first is a fraction)).

Multiple or divide as indicated 2x/4x+2 x 14 x+7/6
otez555 [7]
<span>2x/4x+2 x 14 x+7/6 is unclear.  Do you mean 2/4x, or do you mean  2x
                                                                                                           --------  ??
                                                                                                            4x+2
Use parentheses to make things clearer.

I will assume that you meant to write

   2x
--------- * 14x + 7/6
4x + 2

but am very much unsure if this is correct or not.



Perhaps you meant 

</span>2x/(4x+2) times 14(x+7/6)
<span>
This comes out as follows:

 2x * 14 (x + 7/6)        28x(x + 7/6)        14x(x + 7/6) 
------------------------ = ------------------- = --------------------
       4x+2                        2(2x + 1)              2x + 1         after reduction.

Performing the multiplication, we get            14x^2 + 98/6
                                                                     --------------------
                                                                              2x+1
</span>  

It appears that you're using "x" both as a variable name and as the "multiply" operator.  If so, please don't!  Use " * " to indicate multiplication.
<span>
</span>Please take and share a screen shot of this problem.

If B is the midpoint of AC, and AB=5/2x+12 and AC=12x-4, what is the length of BC?
Setler [38]

Answer:

22

Step-by-step explanation:

We know that AC = 2 * AB so we can write:

12x - 4 = 2(5/2 x + 12)

12x - 4 = 5x + 24

7x = 28

x = 4

Since AB = BC the answer is 5/2 * 4 + 12 = 22.

Tiffany babysits to earn extra money. She charges a fee of $15 per hour for one child, and then an added $30 overall for each ad
Hoochie [10]

Answer: Minimum for $150: 2 Hours

Step-by-step explanation: First, Tiffany charges $30 per additional child. If she babysits for 4 children, you do 30 x 4, which is equal to 120. That would be the cost for the children. Now, if she charges $15 PER HOUR, then you just add up $15 + $15, which is $30, and you add that $30 to the $120. Which is $150. There you have it. If this is wrong, correct me please!
