Solve for b: 2b-9=d please I need help

Tresset [83]

Answer:

Short answer, we need a value for d, longer answer is $b = \frac{d}{2} + 4.5$ (I think)

Step-by-step explanation:

[1] Find b:

2b-9=d

[2] First we need to get b alone:

- $\frac{b-9}{2}$ = $\frac{d}{2}$

- $b - 4.5 = \frac{d}{2}$

[3] Then continue

- Add 4.5 to both sides

- $b = \frac{d}{2} + 4.5$

A loan is paid off in 30 years with a total of $99,000. It had a 3% interest rate that compounded monthly. What was the principa

gayaneshka [121]

Answer:

The principle will be "40295.63". A further explanation is given below.

Step-by-step explanation:

The given values are:

Total amount,

A = 99,000

Rate of interest,

R = 3%

Time period,

T = 30 years

= 360 months

As we know,

⇒ $A=P(1+\frac{{\frac{R}{12} }}{100} )^T$

On substituting the values, we get

⇒ $99000=P(1+\frac{\frac{3}{12}}{100})^{360}$

⇒ $99000=P(1+\frac{\frac{1}{4} }{100}) ^{360}$

⇒ $P=\frac{99000}{(1.0025)^{360}}$

⇒ $P=40295.63$
