The power in C is correct. it is x / 37 So B,C and D all have the correct power. Now you must turn to the base. You are talking about a half life so what is raised to the the correct power must be 1/2

That eliminates D and C both.

A is gone because it has the wrong power.

B <<<< the first part of the question's answer.

Now we will answer the 6 days part.

y = 477 * (1/2) ^(x / 37)
x = 6
y = 477 * (1/2)^ (6/37)
y = 477 * (1/2)^ (0.162 [repeating] )
y = 477 * 0.8397
y = 426.2876 which is confirmed by the answer given. <<<< second answer.

6a-2(4a-5)=40<br>How do I solve it

Elza [17]

Answer:

Distribute, then combine like terms, subtract 10 from both sides of the equation, simplify, divide both sides of the equation by the same term, and simplify to get your solution.

Step-by-step explanation:

1.) Distribute

6−2(4−5)=40

6−8+10=40

2.) Combine like terms

6a-8a+10=40

-2a+10=40

3.) Subtract 10 from both sides of the equation

-2a+10=40

-2a+10-10=40-10

4.) Simplify

subtract the numbers

-2a+10-10=40-10

-2a=40-10

subtract the numbers

-2a=40-10

-2a=30

5.) Divide both sides of the equation by the same term

-2a=30

$\frac{-2a}{-2} =\frac{30}{-2}$

6.) Simplify

cancel terms that are in both the numerator or denominator

$\frac{-2a}{-2} =\frac{30}{-2}$

a= $\frac{30}{-2}$

Divide the numbers

a= $\frac{30}{-2}$

a=-15

a=-15

7.) Solution

a=-15

A briefcase has a three-digit lock code that does not include zero as a digit.

Sladkaya [172]

First it can be a 2,4,6,8. Four numbers.
Then one is removed, leaving three numbers.
Then one is removed, leaving two numbers.
Possibilities for that to happen: 4*3*2 = 24.
Total amount of possibilities: 9*8*7 = 504.
So the answer is A: 24 out of 504.
