Step-by-step explanation:
k - 5 =
k - 1
So, now we combine like terms...
To combine like terms,
(You can either move
k to other side by subtracting both sides by it or you can also move
k to other side by subtracting both sides by that..)
k -
- 5 = -1 (I've moved 1/4)
k - 5 = -1 (After reducing 2/4 ,, you get 1/2)
k -5 = -1 (Adding both sides with 5)
k = 4
= 4 (After rewriting it )
Multiplying both sides by 2.
k= 8
Doneeee....
Hope I made sense!

Answer:...................:)
Step-by-step explanation:
<span>6.5 x 10^6
To answer this question, you need to divide the mass of the sun by the mass of mercury. So
2.13525 x 10^30 / 3.285 x 10^23 = ?
To do the division, divide the mantissas in the normal fashion
2.13525 / 3.285 = 0.65
And subtract the exponents.
30 - 23 = 7
So you get
0.65 x 10^7
Unless the mantissa is zero, the mantissa must be greater than or equal to 0 and less than 10. So multiply the mantissa by 10 and then subtract 1 from the exponent, giving
6.5 x 10^6
So the sun is 6.5 x 10^6 times as massive as mercury.</span>
