Answer:
x=1+2/15
Step-by-step explanation:
4(5x-3)=5x+5=118
We move all terms to the left:
4(5x-3)-(5x+5)=0
We multiply parentheses
20x-(5x+5)-12=0
We get rid of parentheses
20x-5x-5-12=0
We add all the numbers together, and all the variables
15x-17=0
We move all terms containing x to the left, all other terms to the right
15x=17
x=17/15
x=1+2/15
<h3><u>
Answer:</u></h3>
The function N(t) is given as:

<h3><u>
Step-by-step explanation:</u></h3>
Jenny studied the characteristics of two species of bacteria.
The number of bacteria of species A, A(t), after t hours is represented by the function:

The number of bacteria of species B, B(t), after t hours is represented by the function:

N(t) denotes the difference in the number of bacteria; hence N(t) is given by after t hours as:
N(t)=A(t)-B(t)

which on simplifying gives:

Hence,
Answer:
the science fiction books and five mystery books in each package. This is because 6 is the highest common factor of both 48 and 30, and 6 x 8 = 48 and 6 x 5 = 30.
