2t + 3 = -9Subtract 3 from each side:2t = -12Divide each side by 2:t = -6======================-3t - 7 = (-3)(-6) - 7 = +18 - 7= 11.
2t+8-t=-3(t+t)+8-t=-3-8 -8(t+t)-t=-11the -t and the +t cancel outt=-112(-11)+8-(-11)=-3-22+8+11=-3
2t-3-3 = 7 2t = 7+6 2t = 13 t = 6.5
The answer is 21 because if 21 is divided by 3 it equals 7 plus 4 equals 11.
yes, if a=42a+3=112x4=88+3=11
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
2t + 3 = -9Subtract 3 from each side:2t = -12Divide each side by 2:t = -6======================-3t - 7 = (-3)(-6) - 7 = +18 - 7= 11.
2t+8-t=-3(t+t)+8-t=-3-8 -8(t+t)-t=-11the -t and the +t cancel outt=-112(-11)+8-(-11)=-3-22+8+11=-3
2t-3-3 = 7 2t = 7+6 2t = 13 t = 6.5
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
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.
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
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
it equals 28
3tan (2t) = sqrt(3) tan (2t) = sqrt(3)/3 = 0.577 from tangent tables, 2t = 30 degrees t = 15 degrees
