Don't know how this found its way onto a maths page! Chemically it's accurate.
k = 14/43
5k
2k + 17 = 32k = -14k = -7
k=4

The complete ionic equation for the reaction is: Ca^2+(aq) + 2NO3^-(aq) + 2K+(aq) + CO3^2-(aq) --> CaCO3(s) + 2K+(aq) + 2NO3^-(aq)
The expression that equals (3(4h + 2k)) can be simplified by distributing the 3. This results in (3 \times 4h + 3 \times 2k), which simplifies to (12h + 6k). Therefore, the expression is (12h + 6k).
3,000 Get it. It is a math joke. K is often meant as a thousand.
(2k + 3) (2k + 3)
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.
8k +2k + 7 = 10k + 7
2k - 1 = 0 Add 1 to both sides: 2k = 1 Divide both sides by two: k = 0.5
