<h2>Answer:</h2>

$x = \frac{22}{3}$

<h3>alternative form:</h3>

$x = 7 \frac{1}{3} \: or \: x = 7.33333333333$

<h2>Step-by-step explanation:</h2>

$2(3x + 1) = 17 - 3( x - 17) \\ distribute \\ \\ 6x + 2 = 17 - 3x + 51 \\ add \: 3x \: from \: both \: sides \\ \\ 9x + 2 = 17 + 51 \\ add \: 17 \: to \: 51 \\ \\ 9x + 2 = 68 \\ subtract \: 2 \: from \: both \: sides \\ \\ 9x = 66 \\ divide \: both \: sides \: by \: 9 \\ \\ x = \frac{22}{3}$

Sofia takes 10mg of a medicine whose concentration in blood decreases by a factor of one half every day. Let t be the number of

adelina 88 [10]

Answer:

$L = 10(\frac{1}{2} )^{t-4}$

Step-by-step explanation:

If t is the number of days since Sofia took the medication of 10 mg, then the amount of medication in her system after t days will be $S = 10(\frac{1}{2} )^{t}$ .

So, the concentration of medicine in blood decreases by a factor of one half every day.

If we count the number of days from today and Lexi takes 10 mg of the same medicine four days later then the amount of medicine left on her body after t days will be $L = 10(\frac{1}{2} )^{t-4}$ . (Answer)

3. A savings account has a 3% interest rate. (a) Complete the ratio table shown. Show your work. Deposit ($) 100 50 300 Interest

blsea [12.9K]

We all know, savings account have "Compound Interest"

So, Here, On $100 deposit, amount of Interest = $12

So, for $50, it would be: $6

Then, for $300, it is: $36

b) If you deposit $200, then balance after 1 year,
A = P(1 + r)^t

A = 200(1 + 0.03)^1

A = 200(1.03)
A = $206

Now, Balance with $150
A = 150 (1 + 0.03)^1
A = 150(1.03)
A = 154.5

Difference = 206 - 154.5 = $51.5

In short, Your Answer would be: $51.5

Hope this helps!
