C) ![x=\frac{\log(6)}{2\log(3)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B%5Clog%286%29%7D%7B2%5Clog%283%29%7D)
Step-by-step explanation:
![15(3)^{2x}=90\\\\3^{2x}=6\\\\2x=\log_3(6)\\\\2x=\frac{\log(6)}{\log(3)}\\\\x=\frac{\log(6)}{2\log(3)}](https://tex.z-dn.net/?f=15%283%29%5E%7B2x%7D%3D90%5C%5C%5C%5C3%5E%7B2x%7D%3D6%5C%5C%5C%5C2x%3D%5Clog_3%286%29%5C%5C%5C%5C2x%3D%5Cfrac%7B%5Clog%286%29%7D%7B%5Clog%283%29%7D%5C%5C%5C%5Cx%3D%5Cfrac%7B%5Clog%286%29%7D%7B2%5Clog%283%29%7D)
Remember to use the change of base formula, which states that
so that everything has the same base of 10

Answer:
t = ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
Step-by-step explanation:
First, you need to complete the -3 + 1 and then expand the brackets
-3 + 1 = -2
7t -2 - (-2) = -3(1 - 3t)
Now expant the -3(1 - 3t) bracket
-3 * 1 = -3
-3 * -3t = 9t
7t - 2 - -2 = 9t - 3
The two negatives turn positive:
7t - 2 + 2 = 9t - 3
7t = 9t - 3
Move the -3 over to the oposite side, and also move the +7t over to the +9t, making it a negative:
3 = 9t - 7t
3 = 2t
Divide both sides by 2:
t = ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
So the value of t is ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
