Step-by-step explanation:

Ignoring the variable, 20 and 45 have 5 as their GCF. The x doesn't matter because only one of the two numbers has it

First change to standard form of first order linear differential equation and then by finding the appropriate integrating factor

Leokris [45]

Answer:

Step-by-step explanation:

Given is a Differential equation as

$xy' + y = lnx ; y(e)=1$

To bring it to linear form we can divide the full equation by x

$y'+\frac{y}{x} =\frac{ln x}{x}$

This is of the form

y'+p(x) *y = q(x)

p(x) = 1/x

So find

$e^{\int\limits{\frac{1}{x} } \, dx } = e^{ln x} = x$

Solution is

$xy = \int {x*lnx /x } \, dx =xln x -x +C$

Use the initial value as y(e) =1

$e= eln e -e+C\\C=e$

So solution is

$xy =xln x -x+e$

Which is the better buy a 3 pound ham for $5.70 or 5 pounds for $8.75

tekilochka [14]

Answer:

The larger ham is the better buy.

Step-by-step explanation:

In order to determine the better buy, divide both of the prices by their weight to get the price per pound of ham.

5.70/3 = 1.90 per lb

8.75/5 = 1.75 per lb

Therefore the 5 pound of ham is a better buy.

The tank is NOT filled with 8314.5 L of a liquid. I guess you meant The tank is completely filled with 8314.5 grams of liquid." 
(8314.5 g) / (230 L) = 36.15 g/L . Hope this helps!
