Un enfermo diabetico debe administrar dos dosis diarias de 0.0005 L de insulina de por vida. Si en la institucion de seguridad s
Stella [2.4K]

Answer:

60 days

Step-by-step explanation:

Let's call h the daily dose of medication that a diabetic person should administer.

We know that:

h = 0.0005 L/day

We know that 0.03 liters is what the social institution provides.

Then we can raise the following equation:

hx = 0.03

Where x is the number of days

So:

x = \frac{0.03}{h}\\\\x = \frac{0.03}{0.0005}

x = 60 days.

After 60 days you will have to return for more doses

5. -[-2(x-4) - |1-3|] = -2x18
irina [24]

Solving the expression  -[-2(x-4) - |1-3|] = -2x18 we get value of x: x=\frac{3}{19}

Step-by-step explanation:

We need to solve the equation -[-2(x-4) - |1-3|] = -2x18 and find value of x

Solving:

-[-2(x-4) - |1-3|] = -2x18

Multiply -2 with terms inside the bracket

-[-2x+8 - |1-3|] = -2x18

Solving |1-3| we get |-2|=2

-[-2x+8 - 2] = -2x18

-[-2x+6] = -2x18

Multiply (-) sign with terms inside the bracket

+2x-6 = -2x18

Multiply 2x with 18

2x-6 = -36x

Add 36x on both sdides

2x-6+36x =0

38x-6 =0

Add 6 on both sides:

38x =6

Divide both sides by 38

x=\frac{6}{38}

Simplifying:

x=\frac{3}{19}

So, Solving the expression  -[-2(x-4) - |1-3|] = -2x18 we get value of x: x=\frac{3}{19}

Evaluate the equation 4K-10/k=8
solong [7]

Answer:

k = 1 + sqrt(7/2) or k = 1 - sqrt(7/2)

Step-by-step explanation:

Solve for k over the real numbers:

4 k - 10/k = 8

Bring 4 k - 10/k together using the common denominator k:

(2 (2 k^2 - 5))/k = 8

Multiply both sides by k:

2 (2 k^2 - 5) = 8 k

Expand out terms of the left hand side:

4 k^2 - 10 = 8 k

Subtract 8 k from both sides:

4 k^2 - 8 k - 10 = 0

Divide both sides by 4:

k^2 - 2 k - 5/2 = 0

Add 5/2 to both sides:

k^2 - 2 k = 5/2

Add 1 to both sides:

k^2 - 2 k + 1 = 7/2

Write the left hand side as a square:

(k - 1)^2 = 7/2

Take the square root of both sides:

k - 1 = sqrt(7/2) or k - 1 = -sqrt(7/2)

Add 1 to both sides:

k = 1 + sqrt(7/2) or k - 1 = -sqrt(7/2)

Add 1 to both sides:

Answer: k = 1 + sqrt(7/2) or k = 1 - sqrt(7/2)
