Step-by-step explanation:

we can factor out z

so that'll be

z((1/m)-(1/n))=1

divide by the value in parentheses on both sides

z=1/((1/m)-(1/n))

I can't tell if there's more the problem wants you to do. I could rewrite the equation on paper more easily, but I don't have one on hand

Answer: The answer is z=1/((1/m)-(1/n). Abhlnav, I'm sorry about not finding the answer to solve for z, and that’s the reason why you told me to solve for z not m to your algebraic expression to find the answer. Are you very good at mathematics, Abhlnav?

A diver descends to a location of -50 1 over 4 meters relative to the surface of the water. He then descends another 10 1 over 2

Yanka [14]

Answer:

$-60\frac{3}{4}$ meters.

Step-by-step explanation:

To find diver's final location relative to the surface of water we will subtract $10\frac{1}{2}$ from $-50\frac{1}{4}$ because diver dives away another $10\frac{1}{2}$ from his previous location of $-50\frac{1}{4}$ .

$-50\frac{1}{4} -10\frac{1}{2}$

Now we will convert our mixed fraction into improper fraction and then we will find a common denominator.

$\frac{-201}{4} -\frac{21}{2} =\frac{-201-42}{4}$

$=\frac{-243}{4}$

Now let us convert our answer in mixed fraction.

$=\frac{-243}{4}=[tex]-60\frac{3}{4}$ [/tex]

Therefore, diver's final location relative to the surface of the water is $-60\frac{3}{4}$ meters.

Abbi has $400 in $5 bills. If she has 38 bills, how many of them are $20?

Sergio039 [100]

F=5 dollar bills
t=twent dollar bills

38 total bills
f+t=38

400 in bills
400=5f+20t

we have
f+t=38
5f+20t=400
multipy first equation by -5 and add to second equation

-5f-5t=-190
5f+20t=400 +
0f+15t=210

15t=210

divide both sides by 15
t=14

subsitute
t+f=38
15+f=38
f=23

23 five dolar bills
15 twenty dollar bills
