Regroup terms

2 = 7x - 3

Add 3 to both sides

2 + 3 = 7x

Simplify 2 + 3 to 5

5 = 7x

Divide both sides by 7

5/7 = x

Switch sides

The formula for computing compound interest for a principal P that is invested at an annual rate r and compounded annually is gi

Answer:

r ≈ 6%

Step-by-step explanation:

Solving for r when n=2, we have ...

$A=P(1+r)^2\\\\\dfrac{A}{P}=(1+r)^2\\\\\sqrt{\dfrac{A}{P}}=1+r\\\\\boxed{r=\sqrt{\dfrac{A}{P}}-1}$

For the given values of A and P, the value of r is ...

$r=\sqrt{\dfrac{5600}{5000}}-1=\sqrt{1.12}-1\approx 1.0583-1\\\\\boxed{r\approx 6\%}$

Mark walks 1/2 miles in 3/4 of an hour what is the unit rate per hours

lana [24]

Answer:

$unit \: rate = \frac{distance}{time} \\$

substitute:

$unit \: rate = \frac{( \frac{1}{2} )}{ ( \frac{3}{4}) } \\ \\ = \frac{1}{2} \div \frac{3}{4} \\ \\ = \frac{1}{2} \times \frac{4}{3} \\ \\ = \frac{4}{6} \\ \\ = { \underline{ \: \: \frac{2}{3} \: \: miles \: per \: hour \: \: }}$
