3t + 7 = 2t - 5 3t = 2t - 12 t = -12
5t + 2 = 3t - 2t + 5 Collect like terms 5t - 3t + 2t = 5 - 2 4t = 3 t = ¾ Check: 5 x 3/4 = 3¾ + 2 = 5¾; 3x¾- 2x¾ + 5 = 5¾ QED
3tan (2t) = sqrt(3) tan (2t) = sqrt(3)/3 = 0.577 from tangent tables, 2t = 30 degrees t = 15 degrees
T+(3-2t)=4t+1. Assuming the two T's , T and t are the same variable, lets proceed. t+(3-2t)=4t+1 3-t=4t+1 2-t=4t 2=5t last step is yours
R = s + 2t; s = 3tR = 3t + 2tR = 5t
In 2t+8 19
3t + 7 = 2t - 5 3t = 2t - 12 t = -12
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
6t2+25+11 = (3t+11)(2t+1) when factored Use the quadratic equation formula.
2t
19-2t = 7 -2t = 7-19 -2t = -12 t = 6
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.
-2. Look at it as -15 = 2t-11. Add 11 to each side, to get -15+11 = 2t-11+11, or -4=2t. Divide each side by 2, and you get -2.
2t^2+5t-3=0 (2t-1)(t+3)=0 2t-1=0 and t+3=0 t=.5 and t=-3
89+2t = 10t+25 89-25 = 10t-2t 64 = 8t t = 8
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
5t + 2 = 3t - 2t + 5 Collect like terms 5t - 3t + 2t = 5 - 2 4t = 3 t = ¾ Check: 5 x 3/4 = 3¾ + 2 = 5¾; 3x¾- 2x¾ + 5 = 5¾ QED
