The equation of c is an illustration of subject of formula
The equation of c in terms of r and t is c = r - 15/t
<h3>How to determine the equation?</h3>
The equation is given as:
t = 15/(r - c)
Cross multiply
t(r - c) = 15
Divide both sides by t
r - c = 15/t
Subtract r from both sides
-c = -r + 15/t
Multiply both sides by -1
c = r - 15/t
Take LCM
![c = \frac{rt - 15}{t}](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7Brt%20-%2015%7D%7Bt%7D)
Hence, the equation of c in terms of r and t is ![c = \frac{rt - 15}{t}](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7Brt%20-%2015%7D%7Bt%7D)

We can first find the probability of the first person picking Brand A, which would be:
9/6+9
=9/15
=3/5
We can then find the probability of the second person choosing brand A:
(9-1)/(6+9-1)
=8/14
To find the probability they both select Brand A, we could multiply them together:
3/5 x 8/14
=12/35
Therefore the answer would be 12/35.
Hope it helps!
318-47= 271 There are 271 non-fiction books in the library. just subtract 47 from 318 to get the answer.
Answer:
6.5y + 10
Step-by-step explanation:
Combine like terms:
0.5y + 6.5y - 0.5y + 10.5 - 0.5
= 6.5y + 10
I believe it is f(x)=5|x|
I suggest you get a second opinion, though
