Answer:
one solution
Step-by-step explanation:
Given
3x - 2 = 4x + 5 ( subtract 4x from both sides )
- x - 2 = 5 ( add 2 to both sides )
- x = 7 ( multiply both sides by - 1 )
x = - 7 ← the one solution
5 × 6,254= 31,300 is the awnser :)
Step-by-step explanation:
= (15 − 3) ÷ (2 + 1) × (8 − 6)
BODMAS rule
= (12) ÷ (3) × (2)
= (12/3) × (2)
= 4 × 2
= 8

Answer:
a) 16.82 mg
b) 24 days
Step-by-step explanation:
Formula for exponential growth is given as:

Where A is the final population
is the initial population
b is the growth factor
c is the time taken for the growth 'b'
t is the amount of time
Here, We are given the following:
= 5 mg
b = 2 (Given because it doubles)
c = 4 days
a) A = ?
Using the formula:

b) Given
A = 320 mg
t = ?
Using the above formula again:

So, the answers are:
a) 16.82 mg
b) 24 days
