<h2>
<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:
<em>5.195</em>
Step-by-step explanation:
To solve the different operations of a mathematical expression there are rules that must always be followed, that is, there is a hierarchy of operations that must be respected.
The hierarchy of operations works as follows:
First, operations in brackets, brackets or braces are resolved independently.
Next, the powers and roots are realized.
It continues to solve multiplications and divisions.
Finally, the addition and subtraction are carried out, regardless of the order.
6 x 0.9 + 0.1 / 4 -0.23 =
First, multiplications and divisions:
5.4 + 0.025 - 0.23.
Then, addition and subraction:
5.195
The only correct statement is that ratios are not fractions.
These two points have the same x coordinate, 1, so it is a vertical line that passes 1 on the x axis,
the equation of the line is x=1

Answer:
m <B = 41°
Step-by-step explanation:
Fact: complementary angles measures add to 90 degrees
Given: m < A = 2x-19, and m <B = x+7
Find: m <B = ?
Find x
2x-19 + x+7 = 90
2x+x = 90 +19-7
3x = 102
x = 34
Find m <B
m <B = x+7
m <B = 34+7
m <B = 41
