For what value of a does (1/9)a+1 =81a+1 272-a?

AlexFokin [52]

Answer:

-4

Step-by-step explanation:

$\left( \dfrac{1}{9}\right)^{a+1}= 81^{a+1}\cdot 27^{2-a}\\\\\\(3^{-2})^{a+1}=(3^4)^{a+1}\cdot (3^3)^{2-a} \\\\\\3^{-2a-2}=3^{4a+4}\cdot 3^{6-3a} \\\\\\3^{-2a-2}=3^{a+10} \\\\\\-2a-2=a+10 \\\\\\-3a=12 \\\\\\a=-4$

Hope this helps!

5+ 1/7b = -2<br>whats be and explanation<br>(don't get it cause its a fraction)

oee [108]

5+(1/7)b=-2

First subtract 5 from both sides. Our goal is to isolate b.
5+(1/7)b-5= -2-5
(1/7)b= -7

Now multiply both sides by 7 because (1/7)*7= 7/7 or 1.
7* (1/7)b= -7*7
1b= -49

Final answer: b= -49
