!   what is the justification for the step taken from line 2 to line 3? the subtraction property of equality the multiplication property of equality combining like terms on one side of the equation the division property of equality

A. The subtraction property of equality

Step-by-step explanation:

We have to find the rule applied to obtain line 3 from line 2.

Now, line 2 is -4x + 9 = 2x + 10 and line 3 is -6x + 9 = 10.

We can see that the only possible way to get line 3 from line 2 is by subtracting 2x from both the sides.

i.e.  -2x - 4x + 9 = -2x + 2x + 10

i.e. -6x + 9 = 10

Hence, the subtraction property of equality is the justification for getting line 3 from line 2.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
