Rainbow [258]

Answer:

x = -4

Step-by-step explanation:

2x+4(2x+7)=3(2x+4)

Distribute

2x+8x + 28 = 6x +12

Combine like terms

10x +28 = 6x +12

Subtract 6x from each side

10-6x+28 = 6x +12 -6x

4x +28 = 12

Subtract 28 from each side

4x+28-28 = 12-28

4x = -16

Divide each side by 4

4x/4 = -16/4

x = -4

The formula for the future value V (in dollars) of an investment earning simple interest is V=p+prt, where p (in dollars) is the

serious [3.7K]

Answer:

A. $p=\dfrac{V}{1+rt}$

B. $2,307.69

Step-by-step explanation:

You are given the formula

$V=p+prt,$

where V = investment earning simple interest

p = principal,

r = interest rate

t = time

So,

A. $V=p(1+rt)\\ \\p=\dfrac{V}{1+rt}$

B. r = 0.06 (or 6% as percent)

V = $3,000

t =5

so,

$3,000=p+p\cdot 0.06\cdot 5\\ \\3,000=p+0.3p\\ \\1.3p=3,000\\ \\p=\dfrac{3,000}{1.3}\approx 2,307.69$
