If she has finished 20%, she still has 80% to do. So just calculate .8 times 150.

Write a word sentence as an inequality. A number k minus 8.4 is greater than 21.

Travka [436]

Answer: k-8.4>21

Step-by-step explanation: K subtracted by 8.4 is greater than 21, so we start the equality off with our unknown variable K. Because K-8.4 is greater than 21, our symbol faces the direction of K-8.4 (symbol always faces the direction of the greater values).
