Substitute the given values of the variables into the equation. Write True or False to indicate whether the values make the open sentence true or false. Values: x=9 ,y=0.4, z=22
2x + 0.8/y = z - 4

answer:

False

Step-by-step explanation:

2(9) + 0.8/(0.4) = (22) - 4     Substitute in the values

18 + 2 = 22 - 4                      Multiply

20 = 18                                  Simplify

Because 20 is not equal to 18, the equation is false.

4
