15. -(-7y + 12) = 7y - 12

16. 1/a = 16/18
      cross multiply
      16a = 18
      a = 18/16 = 9/8

17. 8x - 12 = 4x + 24
      8x - 4x = 24 + 12
      4x = 36
      x = 36/4
      x = 9

18. -6b > 42           4b > -4
       b < 42/-6          b > -4/4
       b < - 7              b > -1
so b < -7 and b > -1

19. 6 more then the product of 8 and n
      6 + 8n

20. 45 = 3b + 69
      45 - 69 = 3b
      -24 = 3b
      -24/3 = b
      -8 = b

(15) -(-7y + 12) = +7y - 12 (17) 8x - 12 = 4x + 24---> 8x - 4x = 24 + 12 ---> 4x = 36 ---> x = 9 (18) -6b > 42 ---> b<42/-6 ---> b<8 & 4b > 44 --> b> 11. So, 8>b>11 (20) 45 = 3b + 69 --> 3b = -24 ---> b = -8. Not sure what to do for (16) & (19)

First correct answer will get Brainliest, 30 mins to answer! 25 points
MariettaO [177]

Answer:

I'm assuming it would be 3 hours

Step-by-step explanation:

It would be 3 hours because after three hours, the candle that can only burn for 3 hours will have burned out. This leaves the candles that can burn for 4 and 5 hours. I guess if you want to get really specific you could say 3 hours and 59 minutes but I'm not totally sure how your teacher wants the answer

Simplify give ur answer in index form.​
kherson [118]

\frac{( {j}^{4} \:  \times  \:  {j}^{8}) ^{3}  }{( {j}^{9} \:  \div  \:  {j}^{2}) ^{2}   }

  • First we calculate the product of the denominator.

\frac{( {j}^{12}) ^{3}  }{( {j}^{9} \:  \div  \:  {j}^{2}) ^{2}   }

  • Then we calculate the quotient of the numerator.

\frac{( {j}^{12}) ^{3}  }{( {j}^{7}) ^{2}   }

  • We multiply the exponents of the expression.

\frac{ {j}^{36} }{ {j}^{14} }

  • We divide.

\boxed{ \bold{ {j}^{22} }}
