In 2t+8 19
Is |-8|+|3|=|-8+3| true or false?
t - 2t - 3t = 32t - 5t = 32-4t = 32t = -8According to the information given in the question, t can't equal 8.
8
v equals five
In 2t+8 19
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
89+2t = 10t+25 89-25 = 10t-2t 64 = 8t t = 8
2t - 8 = 3t + 12 First you remove the outer numbers from one side of the equation. In this case, 12. But whatever you do to one side, you have to do the same for the other side. 2t - 8 - 12 = 3t Then put all the terms with unknowns on one side. -8 - 12 = 3t - 2t We can simplify this into... -20 = t so... t = -20. hope that helps. :)
Yes, -8 plus plus 3 equals -5. The "plus plus" is equivalent to a positive sign, so -8 plus (+3) equals -5.
(2t - 3)(7t^2 + 8)
89
3t - 1
42
3 plus 1 plus 4 equals 8
12 (t -6) + 8 4 (2t - 1)Distribute: 12t-72+8 8t-4Combine like terms: 12+-64 8tSubtract 12t from each side: -64 -4tMultiply each side by -1: 64 4tDivide each side by 4: 16 tSo t = 16
