Question 1 unsaved which equation has 5 as the value of k? question 1 options: 2.4(k−1.3)=15.12 1.1k−1.8=7.3 1.4(0.7k+2)=2.1 1.8k+3.2=12.2 question 1 unsaved which equation has 5 as the value of k? question 1 options: 2.4(k−1.3)=15.12 1.1k−1.8=7.3 1.4(0.7k+2)=2.1 1.8k+3.2=12.2

The easiest way is to replace "k" with "5" for each of the options and solve to find out which results in a true statement.

2.4(5 - 1.3) = 15.12 → 2.4(3.7) = 15.12 → 8.88 = 15.12 FALSE

1.1(5) - 1.8 = 7.3 → 5.5 - 1.8 = 7.3 → 3.7 = 7.3 FALSE

1.4(.7(5) + 2) = 2.1 → 1.4(3.5 + 2) = 2.1 → 1.4(5.5) = 2.1 → 7.7 = 7.3 FALSE

1.8(5) + 3.2 = 12.2 → 9.0 + 3.2 = 12.2 → 12.2 = 12.2 TRUE!!!

1.8k + 3.2 = 12.2
