-2 + 3b = 5b - 2(2b + 3) How do you solve for b?

1 answer:

6 0

-2 + 3b = 5b - 2(2b + 3) Distribute the -2 through the parentheses.
-2 + 3b = 5b - 4b - 6 Combine like terms
-2 + 3b = b - 6 Bring all "b's" to one side of the equation
-2 + 3b - b = b - b - 6 Combine like terms
-2 + 2b = -6 Bring the 2 to the right side of the equation
-2 + 2 + 2b = -6 + 2 Combine like terms
2b = -4 Isolate b by dividing both sides by 2
b = -4/2 = -2

Answer b = -2

What is √101.6064 in to 1 decimal place and in standard form? NEED ASAP

Dimas [21]

Note that

10² = 100

0.08² = 0.0064

and

101.6064 = 100 + 1.6 + 0.0064

It also happens that

1.6 = 2 • 10 • 0.08

which means

101.6064 = 100 + 1.6 + 0.0064

101.6064 = 10² + 2 • 10 • 0.08 + 0.08²

101.6064 = (10 + 0.08)²

101.6064 = 10.08²

which means

√101.6064 = 10.08

which, to one decimal place, is approximately 10.1.

You wish to buy a house for $295987. The bank offers you a mortgage loan of 3.7% for 25 years. How much will your monthly paym

Allisa [31]

Answer:

Monthly payments: $2446.92

Total expenditure: $734,076.88

Step-by-step explanation:

As the compounding frequency is not stated, it is supposed to be annualy.

The total accumulated value T, including the loan L and the interest is given by the formula

$T=L(1+\frac{r}{n})^{nt}$

where

L = Amount of the loan

r = nominal interest per year. In this case, 0.037

n = compounding frequency, in this case 1 year

t = the length of time the interest is applied. In this case, 25 years.

The total amount after 25 years will be

$T=295987(1+0.037)^{25}=295987(1.037)^{25}=734076.88$

There are 25 times 12 = 300 months in 25 years, so the monthly payments would be

$\frac{734076.88}{300}=\$2446.92$

After the life of the loan, if there are no additional commissions or expenditures, you would have spent the amount of the loan plus interest, that is to say, the amount T previously computed

$734076.88
