2k - 7
k + 7
To write the sum of a number k and 7, you would use the mathematical expression k + 7. This expression represents adding the value of k to 7. In algebraic terms, this is known as an addition operation where k is the addend and 7 is the other addend. The result of this addition operation would give you the sum of k and 7.
7 less than k
Rb+ has a smaller radius than K+ due to increased effective nuclear charge in rubidium. Therefore, K+ has a smaller radius than Rb.
4k = 28 Therefore, 28/4 = 7 k = 7
Any number of the form 84*k, where k is an integer, is evenly divisible.
k is less than or equal to 7
So K > 93...
# 7
If you want to say "Nine is less than a number k," you would write 9<K. If you're asking for an equation, e.g. "Nine less than a number k is equal to that number divided by three," you would write k - 9.
