Answer: x = 11/3

Step-by-step explanation:

Add 5 to both sides.

3x=6+5

3x-5+5=6+5

Add the numbers to both sides -5+5=6+5

3x = 11

Divide both sides of the equation by the same term

3x = 11

3x/3 = 11/3

Cancel terms that are in both the numerator and denominator, which is 3x and 3, and that leaves x

x = 11/3

Hope this helps :)

The gross domestic product (in billions of dollars) can be approximated by p(t)equals564 plus t left parenthesis 36 t supersc

nirvana33 [79]

We have been given gross domestic product (in billions of dollars) can be approximated by $P(t)=564+t(36t^{0.6}-101)$ .

(a) In this part, we need to compute the derivative of this function:

$P'(t)=\frac{d}{dt}(564+t(36t^{0.6}-103))\\P'(t)=\frac{d}{dt}(564)+\frac{d}{dt}(t(36t^{0.6}-103))\\P'(t)=0+57.6t^{0.6}-103\\$

$P'(t)=57.6t^{0.6}-103$

(b) In this part, we need to find the value of P'(45). So, we will substitute t=45

$P'(45)=57.6(45)^{0.6}-103\\P'(45)=565.3924-103\\P'(45)=462.39$ Billion dollars per year.

(c) P'(45)=462.39 represents that 45 years after 1960, that is, in 2005, the GCP was changing at a rate of 462.39 billion dollars per year.

-5/6(8+5b) = 75+5/3 b

Viktor [21]

Answer:

b = - 14

Step-by-step explanation:

Given

- $\frac{5}{6}$ (8 + 5b) = 75 + $\frac{5}{3}$ b

Multiply through by 6 ( the LCM of 6 and 3 ) to clear the fractions

- 5(8 + 5b) = 450 + 10b ← distribute left side

- 40 - 25b = 450 + 10b ( subtract 10b from both sides )

- 40 - 35b = 450 ( add 40 to both sides )

- 35b = 490 ( divide both sides by - 35 )

b = - 14

You paint 13 of a wall in 14 hours. At that rate, how long will it take you to paint one wall?

iogann1982 [59]

Ou paint 1/3 of a wall in 1/4 hour. At that rate, how long will it take you to paint one wall? rate = (area/time)
------
rate = (1/3)/(1/4) = 4/3 job/hr
-----
time for job = 3/4 hr/job = 45 minutes to do the whole job.
