<u>Answer</u><u>:</u><u>-</u></h2>
Jessica sells = 240 books,
Josh sells = 16 books.
<h3>
Given:-</h3>
The price of one book is = $15
Jessica sold 15 times more books than Josh.
In total, they have sold 256 books.
<h3>Solution:-</h3>
We can easily find the answer using variables.
Let,
Josh sold a total of x books whereas Jessica sold a total number of 15x books.
together they sold 16x books.
So we can form the equation
16x= 256
by solving this equation we will get x=16
So, Josh sold 16 books and Jessica sold 16×15=240 books in total.
Answer:
log(x^7·y^2)
Step-by-step explanation:
The applicable rules are ...
... log(a^b) = b·log(a)
... log(ab) = log(a) +log(b)
_____
The first term, 7log(x) can be rewritten as log(x^7). Note that an exponentiation operator is needed when this is written as text.
The second term 2log(y) can be rewritten as log(y^2). These two rewrites make use of the first rule above.
Now, you have the sum ...
... log(x^7) +log(y^2)
The second rule tells you this can be rewritten as ...
... log(x^7·y^2) . . . . . seems to match the intent of the 3rd selection
So D would be going up because it is positive. It is going up 10ft, once again cause the integer is a positive 10. Now E will be going down because it is a negative. Therefore it will go down 15ft for the reason being the integer is negative 15. Hope this helps.
