12 (t -6) + 8 4 (2t - 1)Distribute: 12t-72+8 8t-4Combine like terms: 12+-64 8tSubtract 12t from each side: -64 -4tMultiply each side by -1: 64 4tDivide each side by 4: 16 tSo t = 16
2t - 2 = -4+2 +2 Step 1: Move the 2 to the other side by adding 2 to both sides.-------------2t = -2/2 /2 Step 2: Divide both sides by 2 to get t by itself.-------------t = -1
It is: 2t
-13
if you mean T-3t+2t+4 (T and t is different variables):T-3t+2t+4=T-t+4if you mean t-3t+2t+4:t-3t+2t+4=4
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
75+2t=100-2t 4t=25 t=6.25 So t is 6.25 or 25/4.
A number!
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.
2t
(t + 2)/3 + (t - 4)/6 (the common denominator 6) = [(t + 2)(2)]/(3)(2) + (t - 4)/6 = (2t + 4)/6 + (t - 4)/6 = (2t + 4 + t - 4)/6 = 3t/6 = t/2

After t hours the number of bacteria is 10*2t. So 10*2t > 3000000 => 2t > 300000 => t(log2) > log(300000) => t > log(300000)/(log2) => t > 18.19.. So in just over 18 hours (or 18 hours and 12 minutes, approx).
12 (t -6) + 8 4 (2t - 1)Distribute: 12t-72+8 8t-4Combine like terms: 12+-64 8tSubtract 12t from each side: -64 -4tMultiply each side by -1: 64 4tDivide each side by 4: 16 tSo t = 16
2t - 2 = -4+2 +2 Step 1: Move the 2 to the other side by adding 2 to both sides.-------------2t = -2/2 /2 Step 2: Divide both sides by 2 to get t by itself.-------------t = -1
Rearrange as: 2t2+11t+12 = (2t+3)(t+4) when factored
