Evaluate the expression when k = 1/2. Give your answer as a fraction (or whole number) in lowest terms.
6k + 4
📘 Worked solution
16k + 4 = 6 · 12 + 4Replace k with 1/2.
2= 3 + 4Multiply 6 by the fraction 1/2 first.
3= 142 = 7Rewrite 4 as 8/2 so you can add the two fractions, then simplify to lowest terms.
