The quantity 5 more than a number t is labeled as (5+t) 
Product of 9 and the quantity is labeled as = 9(5+t) which equals 45+9t
Result is less than 6 so the equation becomes
45+9t < 6 
        
             
        
        
        
The answer is 4+5+6=15.Hope that helps. :)
 
        
                    
             
        
        
        
Answer:
C
Step-by-step explanation:
The expression given is a difference of cubes and factors as
a³ - b³ = (a - b)(a² + ab + b²)
8 = (2
 = (2 )³ ⇒ a = 2
)³ ⇒ a = 2
27 = (3y²)³ ⇒ b = 3y²
 = (3y²)³ ⇒ b = 3y²
Hence 2 factors are
(2 - 3y²) and
 - 3y²) and
((2 )² + (2
)² + (2 × 3y²) + (3y²)²)
 × 3y²) + (3y²)²)
= (4 + 6
 + 6 y² + 9
y² + 9 )
)
Hence the factored form of the expression is C

The atomic mass of an atom tells us about how much the atom weighs.
Option A
<u>Step-by-step explanation:</u>
The atomic mass of an atom tells us about the weight of the atoms. An atom can be represented using the mass number denoted as A and atomic number denoted by Z. As atomic number is the number of protons present in the atom, mass number denotes the sum of protons and neutrons present in the atom.
So, the mass number will be approximately equal to the atomic mass. It can be also stated that atomic mass represents the weight of the atoms. The elements are arranged in the increasing order of their atomic mass in the periodic table.
