3+2k= -4(k+4) i need help

Mathematics
1 answer:
Rom4ik [11]3 years ago
3 0

Answer:

k = -19/6

This picture should help you out.

First you distribute -4 among everything in the parenthesis. You will get -4k - 16.

Next you subtract 3 from -16, to get -19.

After that you add 4k to 2k, to get rid of -4k, and you get 6k.

So 6k = -19, and finally you divide 6 on both sides of the equal sign to get k = -19/6.

Hope this helped :)

Bag A has 20% more red balls than bag
Crank

Answer:

50

Step-by-step explanation:

Let a = number of balls in bag A.

Let b = number of balls in bag B.

a = 1.2b

a - 5 = b + 5

1.2b - 5 = b + 5

0.2b = 10

b = 50

Let f be a function defined for t ≥ 0. Then the integral ℒ{f(t)} = [infinity] e−stf(t) dt 0 is said to be the Laplace transform
sveticcg [70]

Answer:

L(f(t)) = 2 \frac{e^{-s} }{s} - \frac{1}{s}

Step-by-step explanation:

let f be a function defined for t ≥ 0

we can write the function f(t) in terms of unit function as follows

f(t) = 2 u,(t) - 1  where

      0≤ t < 1

f(t) = (2 * 0) -1 = -1

when t ≥ 1

f(t) = (2*1 )- 1 = 1

Now the Laplace transform L(F(T)) = 2L( u, (t) ) - L(1)  --------equation 1

this is because L(u,(t)) = \frac{e^{-cs} }{s}

c = 1 hence L(1) = 1/s

back to equation 1

L(f(t)) = 2 \frac{e^{-cs} }{s} -  1/s  laplace transform

also L(u(t) ) = \frac{e^{-s} }{s}

mixas84 [53]

Answer:

0.031

Step-by-step explanation:

The probability of the first being green is 7/20, the second is 6/19 and the third is 5/18.  

7/20 x 6/19 x 5/18

Multiply these together to get the total probability:

0.03070175438

or
