Ira Lisetskai [31]3 years ago
8 0

Answer:

You don't have a question but I'll answer what I can.

half-life = natural log (.5) / k

half-life =  -.693147 / .1247

half-life = 5.561106656

It seems you did not express the k-value properly.

1) A k-value should have a negative value.

2) A k-value should also have units.

For example, the k-value of tungsten 181 is

-0.005723757 / days

When 13 is subtracted from the sum of 2 consecutive numbers the answer is 18 what are the consecutive numbers?
Hitman42 [59]
Let x = the first number
x+1 = the second number

The sum of our two numbers is therefore:  x + (x+1)

When you subtract 13 from the above you get 18 left over.

So our equation is:

x + (x+1) - 13 = 18

Now we can just solve for x:

x + (x+1) = 31

2x + 1 = 31

2x = 30

x = 15

So our first number is 15 and our second number must be 16.

Can someone please help me? And it says “Solve each equation. Then, prove that your answer solves the original equation?
Viefleur [7K]

Step-by-step explanation:

We need to solve each equation.

a. 6c = 30

c = 30/6 = 5

b.

2d-6=12

Adding 6 both sides

2d-6+6=12+6

2d = 18

d = 9

c.

\dfrac{x}{3}+9=2\\\\\dfrac{x}{3}=-7\\\\x=-21

d.

50=14+3m

50-14=3m

36=3m

m = 12

Hence, this is the required solution.
