Hi there!
So for #1:
-12>-36-8x
+36 to both sides of the inequality
24>-8x
Divide both sides by negative 8
Note: when you divide by a negative number, the inequality changes direction.
So you end up with -3-3
For the other two, you forgot to include y and t, so I can't help solve those yet.
<h3><u>given</u><u>:</u></h3>
100 m at a constant speed of 5.

Volume = length x width x height
Volume = 1 1/2 x 2 x 7/2
V = 3/2 x 4/2 x 7/2
V = 12/4 x 7/2
v = 84/6
V = 14
