Consecutive numbers differ by one. So, if
is the first, the three numbers are

The sum of the first and third integer is

Answer: 2.66 × 10⁻¹³
<u>Step-by-step explanation:</u>
First, use the decay formula
where
- A is the final amount (amount left)
- A₀ is the initial amount (amount you started with)
- k is the rate of decay (you need to solve for this)
- t is the time
Given:
- A = 1/2(300) = 150
- A₀ = 300
- k = unknown
- t = 28.8

Next, input the k-value and the new t-value to solve for A.
- A = unknown
- A₀ = 300
- k = -0.0240676
- t = 1440

Answer:

Step-by-step explanation:
Given
-
× -
( negative times negative = positive )
=
×
( cancel the 4 on the numerator and denominator )
= 
Right there 125677 on the left you go 4 ahhbsn
16x-7≤-71
Add 7 to both sides
16x≤-64
Divide both sides by 16
x≤ -4
Hope this helps! :)
