In 2t+8 19
t - 2t - 3t = 32t - 5t = 32-4t = 32t = -8According to the information given in the question, t can't equal 8.
3t+11 = 29 3t = 29-11 3t = 18 t = 6
3t in lb.
5-3t = 0.77 -3t = 0.77-5 -3t = -4.23 t = 1.41
t+8 = 2-3t add 3t to both sides: 4t+8 = 2 take 8 away from both sides: 4t = -6 divide both sides by 4: t = -6/4 = -3/2
In 2t+8 19
3t - 1
t is equal to 6
t - 2t - 3t = 32t - 5t = 32-4t = 32t = -8According to the information given in the question, t can't equal 8.
3t - 15 = -9 3t - 15 (+15) = -9 (+15) 3t = 6 3t (/3) = 6 (/3) t = 2
3t+11 = 29 3t = 29-11 3t = 18 t = 6
3t in lb.
5-3t = 0.77 -3t = 0.77-5 -3t = -4.23 t = 1.41
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. :)
The GCF is 3t.
