5^x + 5^x+1= 150<br> Find x<br> Help me pls i need soon<br> Tksss

raketka [301]

Answer:

$x=2$

Step-by-step explanation:

So we have the equation:

$5^x+5^{x+1}=150$

First, separate the second term:

$5^x+(5\cdot5^x)=150$

Let u equal 5ˣ. So:

$u+5u=150$

Combine like terms:

$6u=150$

Divide both sides by 6:

$u=25$

Substitute back u:

$5^x=25$

Take the base 5 logarithm of both sides:

$\log_5(5^x)=\log_5(25)$

The left cancels:

$x=\log_5(25)$

Evaluate the right:

$x=2$

So, our answer is 2.

And we're done!

PLS HURRY AND HELP ME Larry buys peanut butter and bananas at the grocery store. He spends $3.89 on peanut butter and $9.38 in a

Tamiku [17]

Answer:

x = $5.49 cost of the bananas

Step-by-step explanation:

x = cost of the bananas

$3.89 = cost of the peanut butter

$ 9.38 is the cost of both

Bananas + peanut butter = $9.38

x + $3.89 = $9.38

<u> - $ 3.89 = -$3.89 </u> Subtract $3.89 from both sides

x = $5.49
