Need some more info, what are the dimensions of the bricks?
*Yes, B, C, and D are correct. -15, -10.5, and -7.5 are solutions to x<-7*...........................
......................................................................................................................................
*8y – 24 > –16.............................................................................................................
8y>8 ADD 24 to both sides .......................................................................................
y>1 so C. divide both sides by 8.................................................................................
It is not A because the opposite of subtracting 24 is adding 24. So you add 24 to both sides to undo the subtraction. -16+24=8 Then you divide both sides by 8, which gives you y>1. I think you probably subtracted 24 from -16 instead of adding it.*.........................................

*I'm not sure what to make of the third one, is that a number line or...?*...............................
......................................................................................................................................
*- t/5 ≥15 ........................................................................................................................
-t ≥ 75 MULTIPLY both sides by 5....................................................................................
t ≤ -75 divide both sides by -1, and flip the sign, because when dividing an inequality by a negative number you must flip the sign..............................................................................
So A would be correct. ....................................................................................................
I believe if you divided the 15 by 5 and didn't flip the sign you would get D.*.........................
Also, sorry, my enter key isn't working right, so it's all scrunched together.
Expression example: 15x7
equation example: 15x7=105
2y=-8
We need to clear "y" with inverse operations.
y= -8/2 if 2 was multiplying now is dividing
y= -4
