6t2 - 7t - 5 = (3t - 5)*(2t + 1) So (6t2 - 7t - 5)/(3t - 5) = 2t + 1 provided that t is not 5/3
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

1,000.5 divided by 3 is 333.5
You can work this out simply. First, simplify the problem: -7 = 3t + 2 ... Cancel out the +2.... (by subtracting 2 from each side....) -7 -2 = 3t + 2 -2 ---------------------- -9 = 3t Now that you have a whole number on one side, and your equation on the other... divide both sides by 3 to figure out what "t" is -9 / 3 = 3t / 3 ------------------------------ -3 = t Simple, right? ;D
2t-6=3-t 3t-6=3 Add t to both sides 3t=9 Add 6 to both sides t=3 Divide both sides by 3
it is 91 because T13 is in words 'what is the 13th triangle number?' so T2=3
6t2 - 7t - 5 = (3t - 5)*(2t + 1) So (6t2 - 7t - 5)/(3t - 5) = 2t + 1 provided that t is not 5/3
3t - 15 = -9 3t - 15 (+15) = -9 (+15) 3t = 6 3t (/3) = 6 (/3) t = 2
3t + 9 = 3(t + 3)

S = 3 st + 3t = 6 st = 6 - 3t s = (6 - 3t)/t = 6/t - 3
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
