Please help D=1/3fk solve for k

Mathematics
1 answer:
masha68 [24]3 years ago
8 0

Answer:

<h2>k =  \frac{3D}{f}</h2>

Step-by-step explanation:

<h3>D =  \frac{1}{3} fk</h3>

To solve for k first multiply both sides by 3

That's

<h3>3D = fk</h3>

Next divide both sides by f in order to isolate k

We have

<h3>\frac{fk}{f}  =  \frac{3D}{f}</h3>

Simplify

We have the final answer as

<h3>k =  \frac{3D}{f}</h3>

Hope this helps you

ki77a [65]

Answer:

3 unidades de comprimento

Step-by-step explanation:

O perímetro é definido como a soma de todos os lados.

O perímetro de um quadrado de lado 2x é dado por:

Q=4*2x=8x

O perímetro de um retângulo de comprimento x e largura x² é dado por:

R=2x+2x^2

Para que ambos os perímetros sejam iguais:

R=Q\\8x=2x+2x^2\\x^2=\frac{6}{2}x\\ x=3

O valor de x é igual a 3 unidades de comprimento.

How do you do: -6(6a-5)=-2(8-5a)
devlian [24]

Answer:

a = 1

Step-by-step explanation:

1. distribute the -6 on the left into the parentheses. you should get -36a + 30.

2. on the side right of the =, distribute the -2 to get -16 + 10a.

now it should look like -36a + 30 = -16 + 10a.

3. move the terms over to isolate the a value. subtract 30 to the right side to get -46 (-36a=-46+10a)

4. move the 10a on the right to the left by subtracting it to the other side.

(-46a=-46)

5.divide by -46 to get a=1
