45 Points, Question 2 In Attachment. Asap if possible.

Masja [62]

Answer: x = $\frac{-5}{2}$

Step-by-step explanation:

$3^{4x-5}$ = $(\frac{1}{27}) ^{2x+10}$

1/27 can be written in index form as $3^{-3}$

The equation then becomes:

$3^{4x-5}$ = $(3^{-3})^{2x+10}$

Equating the coefficient

4x - 5 = -3 ( 2x + 10)

4x - 5 = -6x - 30

10x = -30 + 5

10x = -25

x = -25/10

x = -5/2

x = - 2.5

Answer:

The best estimate for the money in Karita's account now is $151.

Step-by-step explanation:

Given:

Karita had $138.72 in her checking account.

She wrote checks for $45.23 and $18.00.

Then she made a deposit of $75.85 into her account.

Now, to find the best estimate for the money in Karita's account now.

<em>Initial account = $138.72.</em>

<em>Deducted amount = $45.23+$18.00=$63.23.</em>

So, the amount after deduction:

$138.72 - $63.23 = $75.49.

Now, the amount after deposit:

$75.49 + $75.85 = $151.34.

Therefore, the best estimate for the money in Karita's account now is $151.
