Answer:

\large\boxed{x=-3i}

Step-by-step explanation:

(x-i)^5=32(x+i)^5\\\\(x-i)^5=2^5(x+i)^5\qquad\text{use}\ (ab)^n=a^nb^n\\\\(x-i)^5=\bigg(2(x+i)\bigg)^5\iff x-i=2(x+i)\qquad\text{use distributive property}\\\\x-i=2x+2i\qquad\text{add}\ i\ \text{to both sides}\\\\x=2x+3i\qquad\text{subtract 2x from both sides}\\\\-x=3i\qquad\text{chnage the signs}\\\\x=-3i

inysia [295]
The first thing we must do for this case is to define a variable.
 We have then:
 x: weight of each pallet with cement
 We then have the following equation:
 16x = 4856
 Clearing x we have:
 x = (4856) / (16)
 x = 303.5 punds
 Answer:
 
each pallet with cement weigh:
 
x = 303.5 punds

Jane needs to miss fewer than 1/6 of the words on her spelling list.  If there are 18 words, how many can she miss?  Explain.
rjkz [21]
She would have to miss 1 or 2 because 1/6 of 18 is 3 so less than 3 is 2 or 1

hope that helps!

What is solution of 5+3(y-4)=5(y+2)-y
gulaghasi [49]

Answer:

y = -17

Step-by-step explanation:

5 + 3(y - 4) = 5(y + 2) - y        Distribute

5 + 3y -12 = 5y + 10 - y          Combine like terms

-7 + 3y = 4y + 10

+7                 +17                    Add 17 to both sides

3y = 4y + 17

-4y   -4y                                 Subtract 4y from both sides

-y = 17                                     Divide both sides by -1

y = -17

I have way more questions than this answer them if you want pleaseee!!
aliina [53]

The right answer is Option C.

Step-by-step explanation:

Given inequality is

6(2x-1)  > 24

Solving the inequality

6*2x-1*6>24\\12x-6>24

Adding 6 on both sides

12x-6+6>24+6\\12x>30

Dividing both sides by 12

\frac{12x}{12}>\frac{30}{12}\\x>\frac{5}{2}

Therefore,

x>\frac{5}{2}

The right answer is Option C.
