2k plus 3 equals 11 what is k?
Well, honey, if you want to solve for k, just isolate the variable by subtracting 3 from both sides of the equation. That leaves you with 2k equals 8. Then, divide both sides by 2 to find that k equals 4. Math doesn't have to be a headache, darling.
What does odd X even equal?
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.
What is 2k x k?
Oh, dude, 2k x k is just 2k^2. It's like multiplying 2 by k and then squaring the result because math loves to keep things interesting. So yeah, 2k x k equals 2k^2, but like, who's really keeping track anyway?
-3k plus 10 equals k plus 2?
-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
What is the answer to 35 plus 2k equals 9k?
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
