<span>(-5w^10+10w^8+5w^6)/(5w^5)
to divide we can factor out 5w^5 from the numerator
=[5w^5(-w^5+2w^3+w)]/(5w^5)
5w^5 will cancel out to have
=(-w^5+2w^3+w)
Hence
Answer:</span>(-w^5+2w^3+w)<span>

IF -2/5 + -1/4 IS IN PARENTHESES:
skip this part if its not
(1/2) / (-2/5 - 1/4)
(-2/5 - 1/4) is equivalent to (-8/20 - 5/20) = -13/20
substitute -13/20 for (-2/5 - 1/4)
1/2 / -13/20
remember that division is the inverse of multiplication, so if we flip the second fraction, we can change the division sign to multiplication (when doing this, never flip the first fraction, you will not get the right answer)
1/2 * -20/13
simplify -20/2 to get -10
1 * -10/13 = <u>-10/13</u>
IF -2/5 + -1/4 IS NOT IN PARENTHESES:
1/2 / -2/5 +-1/4
PEMDAS : multiplication/division comes before addition / subtraction
1/2 / -2/5 = (apply the flip rule : read the chunk of text above if you don't know what it is) 1/2 * -5/2 = -5/4
subtract 1/4 form -5/4 now
-5/4 - 1/4 = -6/4
simplify
= <u>-3/2</u>
Answer:
The answer is below
Step-by-step explanation:
1) -3x = 42
Divide both sides by -3
-3x/ -3 = 42 / -3
x = -14
Answer: p.x=-14
2)

Answer: j. x=54
3) 5x = 105
Divide both sides by 5
5x/ 5 = 105 / 5
x = 21
Answer: n. x=-21
4) x+37=-25
add -37 to both sides
x+37 - 37 =-25 - 37
x = -62
Answer: d. x=-62
5) x-42=-15
add 42 to both sides
x-42 + 42 =-15 + 42
x = 27
Answer: k. x=27
6)x - (-12) = -4
x + 12 = -4
add -12 to both sides:
x + 12 - 12 = -4 - 12
x = -16
Answer: f. x = -16
7) x - (-6) = 5
x + 6 = 5
add -6 to both sides:
x + 6 - 6 = 5 - 6
x = -1
Answer: r. x = -1
8)8-x = -12
8 - x + x + 12 = -12 + x = 12
x = 8 + 12
x = 20
Answer: c) x = 20
9) -9 - x = -6
x = -9 + 6
x = -3
Answer: s. x =-3
10) -6 + x = 17
x = 17 + 6
x = 23
Answer: a. x =23
11)

Answer: b. x = -378
12) -16 = x - 8
x = -16 + 8
x = -8
Answer: q. x = -8
13) -25 = x + 17
x = -25 - 17
x = -42
Answer: h. x = -42
14) 36 = 8 - x
x = 8 - 36
x = -28
Answer: g. x = -28
15) -x + 6 = 11
x = 6 - 11
x = -5
Answer: m. x = -5
16) -x + 8 = 4
x= 8 - 4
x = 4
Answer: e. x =4
17) 16 = 4 -x
x = 4 - 16
x = -12
Answer: o: x = -12
18) 85 = -5x
x = 85/ -5
x = -17
Answer: l. x= -17
19) 21 = -x/7
x = 21 * -7
x = -147
Answer: i. x = -147
(8/9)^2 is just 8/9 squared, or 8/9 * 8/9. This is 64/81, and cannot be reduced. This is therefore our answer.
