2t + 3 = -9Subtract 3 from each side:2t = -12Divide each side by 2:t = -6======================-3t - 7 = (-3)(-6) - 7 = +18 - 7= 11.
Oh, dude, you just gotta isolate that "t" variable. So, first, subtract 3 from both sides to get 2t = -14. Then, divide by 2 and you'll find out that t = -7. Easy peasy lemon squeezy.
2t
In 2t+8 19
75+2t=100-2t 4t=25 t=6.25 So t is 6.25 or 25/4.
2t + 3 = -9Subtract 3 from each side:2t = -12Divide each side by 2:t = -6======================-3t - 7 = (-3)(-6) - 7 = +18 - 7= 11.
19-2t = 7 -2t = 7-19 -2t = -12 t = 6
2t+3 = -11 Subtract 3 from both sides: 2t+3-3 = -11-3 2t = -14 Divide both sides by 2 in order to find the value of t: t = -7
3t + 7 = 2t - 5 3t = 2t - 12 t = -12
If you mean t(t+7) = 4(3+2t), then it is factored. If you meant solve for 't', then the solution is t = t2 - 12.
3tan (2t) = sqrt(3) tan (2t) = sqrt(3)/3 = 0.577 from tangent tables, 2t = 30 degrees t = 15 degrees
9t + 5 = 7 - 2t Subtract five from both sides: 9t = 2 - 2t Add 2t to both sides: 11t = 2 Divide both sides by 2 t = 2/11 or about .1818
Oh, dude, you just gotta isolate that "t" variable. So, first, subtract 3 from both sides to get 2t = -14. Then, divide by 2 and you'll find out that t = -7. Easy peasy lemon squeezy.
2t^2+5t-3=0 (2t-1)(t+3)=0 2t-1=0 and t+3=0 t=.5 and t=-3

R = S + 2T S = 3T .... substitute R = (3T) + 2T R = 5T
