When solving negative one over five -1/5 (x − 25) = 7, what is the correct sequence of operations
aleksandr82 [10.1K]

The solution would be like this for this specific problem:

 

\left( { - 5} \right)
\cdot \left( { - \frac{1}{5}} \right) \cdot \left( {x - 25} \right) = 7 \cdot
\left( { - 5} \right)

 

 

\left( { - 5} \right)
\cdot \left( { - \frac{1}{5}} \right) = 1

 

The correct sequence of operations when solving negative one over five (x − 25) = 7 would be multiply each side by −5, and adding 25 to each side.

Tom has 28 milk chocolates and emily has 24 dark chocolates they have to divide these chocolates into small packets that each ha
Nutka1998 [239]
28+24=52
So we make a sum of what's going to equal 52 in small packets.
I found 4x13=52. 13 would be the number of packets......
BUT!! Since it MUST be equal dark and milk and we have 28 and 26,
you would have to eliminate 1 pack because all 4 would be milk chocolate.
So that is only 12 packets.
4 per pack so that would be 2 dark and 2 milk per packet.

What segment is congruent to AC?<br> A. BD<br> B. BE<br> C. CE<br> D. none
Phoenix [80]
You can find the segment congruent to AC by finding another segment with the same length. So first, you need to find the length of AC.

   C - A = AC
0 - (-6) = AC   Cancel out the double negative
  0 + 6 = AC
        6 = AC

Now, find another segment that also has a length of 6.

   D - B = BD
2 - (-2) = BD   Cancel out the double negative
  2 + 2 = BD
        4 = BD
        4 ≠ 6

   E - B = BE
4 - (-2) = BE   Cancel out the double negative
  4 + 2 = BE 
        6 = BE
        6 = 6

So, the segment congruent to AC is B. BE .

An electronic device that previously sold for $21.00 has been reduced to $17.43. The price reduction, rounded to the near east w
svet-max [94.6K]

The percentage of reduction is 17%

<u>Explanation:</u>

Original price = $21

Reduced price = $17.43

Percentage of reduction = ?

Difference in price = $21 - $17.43

                               = $3.57

Percentage of reduction = \frac{difference}{original} X 100

                                         = \frac{3.57}{21} X 100\\\\= 17

Therefore, percentage of reduction is 17%
