Vamos resolver sua equação passo a passo.

10-7c=10+2(3-5c)

Etapa 1: simplifique os dois lados da equação.

10-7c=10+2(3-5c)

10+-7c=10+(2)(3)+(2)(-5c)(Distribuir)

10+-7c=10+6+-10c

-7c+10=(-10c)+(10+6)(Combine os termos semelhantes)

-7c+10=-10c+16

Etapa 2: adicione 10c a ambos os lados.

-7c+10+10c=-10c+16+10c

3c+10=16

Etapa 3: subtraia 10 de ambos os lados.

3c+10-10=16-10

3c=6

Etapa 4: divida os dois lados por três.

c=2

The solutions to the equation $3-k=\sqrt{3k+1}$ are k = 1 and 8

The given equation is:

$3-k=\sqrt{3k+1}$

Square both sides of the equation

$(3-k)^2=3k+1$

Expand the left side of the equation above

$(3-k)^2=3k+1\\\\(3-k)(3-k)=3k+1\\\\3^2-3k-3k+k^2=3k+1\\\\9-6k+k^2=3k+1$

Write the quadratic equation in standard form

$k^2-6k-3k+9-1=0\\\\k^2-9k+8=0\\\\$

Factor the quadratic equation

$(k-8)(k-1)=0$

Use the zero product property

k - 8 = 0

k = 8

k - 1 = 0

k = 1

The solutions to the equation $3-k=\sqrt{3k+1}$ are k = 1 and 8

About how many times larger than the diameter of a red blood cell is the diameter of a grain of sand? Write your answer using a

Alchen [17]

Answer:

$0.29\cdot10^3$

Step-by-step explanation:

Red blood cell: $8.4\cdot 10^{-6}$

Grain of sand: $2.4\cdot 10^{-3}$

The "how many times larger" part can be figured out by forming a ratio between the two diameters above:

$\frac{2.4\cdot 10^{-3}}{8.4\cdot 10^{-6}} = \frac{2.4}{8.4}\cdot\frac{10^{-3}}{10^{-6}}\approx 0.29\cdot 10^{-3-(-6)}=0.29\cdot10^3$

Note that dividing the powers of ten corresponds to subtracting the denominator power from the numerator power of 10.
