9=3^2
3^(2x)=(3^2)^(3x-4)
3^(2x)=3^(6x-8)
2x=6x-8
0=4x-8
8=4x
2=x
Answer:

Step-by-step explanation:

<u>1.Find the LCM(Least Common Multiple).</u>
That would be 20.
<u>2.Multiply so all denominators are equal.</u>

<u>3. Add</u>
<u></u>
<u>4. Simplify</u>
<u></u>
180 - 149 = 31
x/100 *149 = 31
1.49x = 31
x= 31/1.46 = 20.81 %
210 take 126/3 = 42 take 42x5 = 210
The answer is d I just did that paper mark me Brainly
