Solve for a over the real numbers:
a^2/3 - 1/a = a^2/6

Bring a^2/3 - 1/a together using the common denominator 3 a:
(a^3 - 3)/(3 a) = a^2/6

Cross multiply:
6 (a^3 - 3) = 3 a^3

Expand out terms of the left hand side:
6 a^3 - 18 = 3 a^3

Subtract 3 a^3 - 18 from both sides:
3 a^3 = 18

Divide both sides by 3:
a^3 = 6

Take cube roots of both sides:
Answer:  a = 6^(1/3)

Umnica [9.8K]

Answer:

  8 years

Step-by-step explanation:

The first company's offer is $8000 lower, but the raises are $1000 higher each year. It will take 8000/1000 = 8 years for the salaries to be the same.

__

If you like, you can write an equation that will tell you the same thing.

  28000 +3000y = 36000 +2000y

Subtract 28000+2000y from both sides:

  3000y -2000y = 36000 -28000

  1000y = 8000

  y = 8000/1000 = 8

Explain how you would estimate to subtract 189 from 643
vaieri [72.5K]
You would round both numbers and subtract. For example 189 can round to 200 and 643 would round to 600. Now just subtract, 600-200=400

43. A) I think its 2 pairs of shoe and one shoe is left because the guy either lost it, or just has an extra shoe. 43. B) If one of the pairs is missing a shoe then there is 4 shoes because there was already one shoe missing a pair but it's still there so if one pair is missing one completely like, it's not there then there's five. 44. 4xy²+3x-5. 45. I am not good at this. But I think: Sally has x beans she gave 8 to Marcus. How many does Sally have now? 46. Yes because whatever y is times one is still going to be y and according to pemdas its multiplication the addition so therefore it would me 1xy then it would be yx4 and it would still be the same answer.
