b)41/48

<em>Step-by-step explanation:</em>
<u>-Question A-</u>
1) Rephrase the problem to look like this:
3/7*28/15*5/14 <-- when dividing fractions you actually multiply by the reciprocal (opposite)
2) Multiply across the above phrase:
420/1470
3) Simplify your fraction:
2/7
There is nothing else to be done with 2/7 and thus it is your final answer.
<u></u>
<u>-Question B-</u>
1) Get the denominator of all 3 fractions to the same Least Common Denominator (48):
42/48 + 3/48 - 4/48
2) Do the arithmetic in the phrase above:
41/48
41/48 cannot be simplified and thus is your final answer
(2 + a) = (a + 2) it's commutative property
(a + 2) - 7 = a + (2 - 7) it's associative property
2 - 7 = -5 it's subtraction
Answer: distributive property { a(b + c) = ab + ac }
Answer:
D.
Step-by-step explanation:
Add 2 to both sides:
Add half of the coefficient of the x, squared to both sides:
Simplify:
Complete the square:
![x-5=\sqrt[]{44}](https://tex.z-dn.net/?f=x-5%3D%5Csqrt%5B%5D%7B44%7D)
or ![x-5=-\sqrt[]{44}](https://tex.z-dn.net/?f=x-5%3D-%5Csqrt%5B%5D%7B44%7D)
or 
If you would like to know the solution to the equation, you can calculate this using the following steps:
4/5n - 3/5 = 1/5n /*5n
4 - 3/5 * 5n = 1
4 - 3n = 1
4 - 1 = 3n
3 = 3n
n = 1
The correct result would be n = 1.
