Answer:

73

Step-by-step explanation:

First add the one with the same denominator.

15\frac{9}{12} + 23\frac{3}{12} = 38\frac{12}{12} = 39

8\frac{13\\}{17} + 25\frac{4}{17} = 33\frac{17}{17} = 34

Then add the answers of those equations.

39 + 34 = 73

What is the slope of the graph of this function?
sladkih [1.3K]

Answer:

C) - 7/3

Step-by-step explanation:

Slope is rise over run, rise/run, and your line means your slope will be negative. So, you will first count straigt down from your firt point until you reach the line of the second point, which is 7. Next, you would count/run to the point, which is 3. Rise/run = -7/3. I hope this helps :)

Solve PV= nRT for n.<br> A. PV/RT=n<br> B. RT- PV=n<br> C. RT/PV=n<br> D. PV- RT=n
Ilia_Sergeevich [38]

Answer:

A - PV/RT = n

Step-by-step explanation:

The objective is to isolate the variable n which represents moles. To do so, you must get rid of the surrounding variables.

Surrounding n, the variables R (gas constant) and T (temperature) are shown being multiplied with n. To get rid of them, you must do the inverse which is to divide.

PV = nRT

Divide both sides by R

PV/R =nT

Divide both sides by T

PV/RT = n

And now, the variable n has been isolated and the new equation to solve for moles is presented.

Hope this helps!
