IHOPE THIS CORELRECT ANSWER
<span>X= -0.083….. as
fraction.
=> x = -0.083…
=> Let 10x = -0.83
Therefore, 10x and x = -8.3… and -0.083….
Now let’s subtract both number
=> 9x = -7.47 (let’s round off -7.47 to 7.5)
=> 9x = - 7.5 ( fraction of -7.5 = -15/2)
=> 9x = 15/2
=> x = 16/18
=> therefore x= 16/18 or 5/6</span>
Answer:
79 sociology textbooks and 138 biology textbooks
Step-by-step explanation:
Create a system of equations, where b is the number of biology books and s is the number of sociology books:
b + s = 217
b = s + 59
Solve by substitution by substituting s + 59 for b into the first equation:
b + s = 217
s + 59 + s = 217
Add like terms and solve for s:
2s = 158
s = 79
So, there were 79 sociology books. To find the number of biology books, substitute 79 in for s into the equation b = s + 59
b = s + 59
b = 79 + 59
b = 138
So, 79 sociology textbooks and 138 biology textbooks were sold.
