Yes, that looks good.
That's 180 degrees plus every multiple of 360 degrees more.
2k + 17 = 32k = -14k = -7
2k + 3 = 11(- 3 from both sides)2k = 8(divide both sides by 2)k = 4
Don't know how this found its way onto a maths page! Chemically it's accurate.
2k - 1 = 0 Add 1 to both sides: 2k = 1 Divide both sides by two: k = 0.5
If by K2 you are not referring to the mountain, the distributive property of multiplication tells us K * 2 = 2 * K.Therefore: K2 + 2K + 4K = 2K + 2K + 4K = 8K
35 + 2k = 9k subtract 2k from each side 35 + 2k - 2k = 9k - 2k 35 = 7k divide both sides integers by 7 35/7 = (7/7)k 5 = k check in original equation 35 + 2(5) = 9(5) 35 + 10 = 45 45 = 45 checks out
==> 3k+14=k ==>3k-k=-14 ==>2k=-14 ==>k=-7 ans...
It can be simplified to: 9k
3k-1=k+2 2k=3 k=3/2=1.5
Let even be of the form 2k and odd be of the form 2k+1. Then odd * even becomes 2k*2k+1, or 4k^2 +2k. This can be written as 2(k^2 + k), which is of the form 2k. Therefore, odd X even equals even.
-4k + 10 - k + 2 = 2k + 4k + 18Combine all the 'k' terms on the left side:-5k + 10 + 2 = 2k + 4k + 18Combine all the 'k' terms on the right side:-5k + 10 + 2 = 6k + 18Combine the numerical terms on the left side:-5k + 12 = 6k + 18Add 5k to each side:12 = 11k + 18Subtract 18 from each side:-6 = 11kDivide each side by 11:k = -6/11
neg(-k) + neg(-k) = k + k = 2k = 4
-4. -3k+10=k+2.... First we have to move the K to one side -3k+10=k+2 __________ This will reduce -3k to -2k and k+2 to just 2 K -2k+10=2 Now we have to subtract 10 to both sides as to get k alone. -2k+10=2 ________ Now we should have -2k on one side and 2-10 on the other. -10 -2k=2-10....... 2-10= 8. We have to get -2k into just K on itself so we divide by 2. -2k=-8 ______ Your answer is 4. You have to do one side what you do the other. 2
6 + 2K = 11 subtract 6 from each side - 6 + 6 + 2K = 11 - 6 2K = 5 divide the integers both sides by 2 K = 5/2 check 6 + 2(5/2) = 11 6 + 10/2 = 11 6 + 5 = 11 11 = 11 checks
2k - 3k - m + 2m = -k + m
There is not a "reverse" - whatever that may mean. The solution is x = (-0.6662 + 2k*pi) radians where k is an integer.
Yes, such solution contains 2K+ + SO4-- ions
2k = 5k-30 Subtract 5k from both sides: -3k = -30 Divide both sides by -3 to find the value of k remembering that a minus divided into a minus becomes a plus: k = 10
Is the following what you are claiming? 2k = 2k+1 -1 20 not equal 20+1 - 1 21 not equal 21+1 -1
Its 18k plus 2k for your kit
Potassium reacts with water to yield potassium hydroxide and hydrogen. 2K + 2H2O --> 2KOH + H2 The heat from this reaction will likely ignite the escaping hydrogen.
The above expression can be simplified to:14n-2k
Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
9 - 2k - 3 = k Add 2k to both sides: 9 - 3 = k + 2k Combine like terms: 6 = 3k Divide both sides by 3: 2 = k
