8t-6 <= 9t + 10 -16<= t T is greater than or equal to negative 16
Since 1 ton is equal to 2,000 lb, 8T is equal to 16,000 lb.
The expression 15-t plus 8t-13 simplifies to 7t + 2.
15t = 17 + 8t -24 15t - 8t = 17 - 24 7t = -7 t = -1
12(t+6)+8=4(2t-1)+2t 12t+72+8=8t-4+2t 12t-2t-8t=-72-8-4 2t=-84 2t/2=84/2 t=42
8t-6 <= 9t + 10 -16<= t T is greater than or equal to negative 16

7s plus 8t plus 10s plus 12t can be simplified to 17s plus 20t.
Yes, a linear equation in t.
Since 1 ton is equal to 2,000 lb, 8T is equal to 16,000 lb.
The expression 15-t plus 8t-13 simplifies to 7t + 2.
15t = 17 + 8t -24 15t - 8t = 17 - 24 7t = -7 t = -1
-3t3 + 23t2 + 8t = -t(3t2 - 23t - 8) = -t(3t + 1)(t - 8)
12(t+6)+8=4(2t-1)+2t 12t+72+8=8t-4+2t 12t-2t-8t=-72-8-4 2t=-84 2t/2=84/2 t=42
t=-2
8t + 5 = 6t + 1,subtract 6t an 5 from each side,2t = -4t = -2Checking, 8t + 5 = -16 + 5 = -11 and 6t +1 = -12 + 1 = -11
8t^2 - 11t - 4
