<h3>Answer:</h3>

<h3>Step-by-step explanation:</h3>

$\sf \frac{7 + 2x}{3} = 5$

$\sf = 7 + 2x = (5 \times 3)$

$\sf = 7 + 2x = 15$

$\sf = 2x = 15 - 7$

$\sf = 2x = 8$

$\sf = \: \: \: x = 8 \div 2 \\ \sf x = 4$

Suppose you want to have $400,000 for retirement in 35years. Your account earns 4% interest.

Sedaia [141]

$\begin{equation*} \$437.76 \end{equation*}$

1) This is a question for Annuity usage. Note that we'll need the following formula below:

$\begin{gathered} P=\frac{A(\frac{r}{n})}{\lbrack(1+\frac{r}{n})^{nt}-1\rbrack} \\ P=\frac{400000(\frac{0.04}{12})}{\lbrack(1+\frac{0.04}{12})^{12\cdot35}-1\rbrack} \\ P=\frac{400000\cdot\frac{0.04}{12}}{\left(1+\frac{0.04}{12}\right)^{35\cdot\:12}-1} \\ P=\frac{400000\cdot\frac{0.04}{12}}{1.0033^{420}-1} \\ P=437.76563...\approx\$437.76 \end{gathered}$

Note that P is the value you'll need to deposit each month so that in 35 years you'll have $400,000 for your retirement.

A doctor orders 150 mg of aspirin to be taken by 12.4 Ib infant every 9 hours. How many mg of the drug does the infant take in 3

andreev551 [17]

Answer: 600 mg in 36 hours.

Step-by-step explanation:

1. Divide 36 by 9, so you know how many times the infant has to take the medicine. 36/9=4

2. Multiply 150x4 because the infant has to take 150 mg, each dosage. 150x4=600.

3. Your final answer is 600 mg. (You did not need the infant's weight in this problem. So, that's why it was not worked in.)

Hope this helps. :)
