Check 1/1 pt Info Details In which of the following equations is the distributive property properly applied to the equation: 21(y+19)=2421(y+19)=24 ? Correct. Since the distributive property allows us to distribute the multiplication of an entire expression to each of the terms of the expression separately, 21y+399=2421y+399=24 is correct.  21y+399=2421y+399=24  21y+19=2421y+19=24  21y+399=50421y+399=504  y+399=24y+399=24 Correct Question HelpQuestion 7:  Message Message instructor Correct Question 8 Check 1/1 pt Info Details Solve for xx . 5(7x−1)−9(3x)=135(7x-1)-9(3x)=13 x=x= $2.25$2.25 Correct If needed, enter your answer as a reduced fraction.
