P + nx=rx-e (solve for x)

Mathematics
1 answer:
lorasvet [3.4K]3 years ago
8 0

Answer:

(p+e)/(r-n) =  x

Step-by-step explanation:

p + nx=rx-e

Add e to each side

p +e+ nx=rx-e+e

p +e+ nx=rx

Subtract nx from each side

p +e+ nx - nx=rx-nx

p+e = rx -nx

Factor out x

p+e = x(r-n)

Divide each side by (r-n)

(p+e)/(r-n) =  x(r-n)/(r-n)

(p+e)/(r-n) =  x

HURRY PLEASE!<br> (g+2)^5
KengaRu [80]

Step-by-step explanation:

We need to use the binomial theorem/Pascal's triangle here.

(a+b)^5 = (5 choose 0)a^5 + (5 choose 1)a^4*b + (5 choose 2)a^3*b^2 + (5 choose 3)a^2*b^3 + (5 choose 4)a*b^4 + (5 choose 5)b^5.

5 choose 0 = 1

5 choose 1 = 5

5 choose 2 = 10

5 choose 3 = 10

5 choose 4 = 5

5 choose 5 = 1

And 1, 5, 10, 10, 5, 1, is the (5+1) = 6th row of pascal's triangle.

Therefore we get

g^5 + 5g^4*2 + 10g^3*2^2 + 10g^2*2^3 + 5g*2^4 + 2^5

which is

g^4 + 10g^4 + 40g^3 + 80g^2 + 80g + 32

Or, you could do the slow way, by just doing (g+2)(g+2)(g+2)(g+2)(g+2)

What's the answer ? To this question
Airida [17]
You could use the equation y=mx+b

Find the slope of the two coordinates. I would personally suggest using stack and subtract:

(0,2) 2-5 -3 3
(2,5) -------= ------= -----
0-2 -2 2

We have the slope but we need to find the y-intercept.

y=3
--x+b
2

Plug one of the coordinates in the constructed equation above:

2=3
-- (0)+b
2

2=0+b
-0=-0
------------
b=2

We found the slope and y-intercept. Now we have our complete equation. The equation is:

y=3
--x+2
2

At 9:00 a.m. marsha found a parking meter that still had 5 minute until it expired. She quickly put a quarter, 1 dime, and a nic
LUCKY_DIMON [66]
1 quarter + 1 dime + 1 nickel = 25¢ + 10¢ + 5¢ = 40¢

Each 5<span>¢ buys 15 minutes.  How many ' 5</span>¢ ' are in 40<span>¢</span> ?

40/5 = 8 of them.  So the (quarter+dime+nickel) can buy 8 x 15 minutes = 2 hours.

Starting at 9:00 AM, the meter had 5 minutes left on it, and Marsha bought
another 2 hours.  So now the meter is good until 2 hours and 5 minutes
after 9:00 AM . . . . . 11:05 AM.
