I believe it is 1/6 but i'm not sure .
hope that helped
Answer:
The solution is the point (18,0)
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system by substitution
substitute equation B in equation A
solve for x
Adds (1/3)x both sides
Adds 6 both sides
<em>Find the value of y</em>
substitute the value of x in equation A or equation B
therefore
The solution is the point (18,0)
The percent by which the sales of horror books is greater than sales of cookbook is 1.85% approx.
<h3>How to find the percentage from the total value?</h3>
Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
Given that:
Genre number sold
- Romance 52
- Horror 55
- Fantasy 60
- Biography 57
- Humor 58
- Cookbook 54
Let we have:
Number of horror books sold = P% greater than number of cookbooks sold
55 = P% greater than 54
55 = 54 + P% of 54
1 = P% of 54
Thus, the percent by which the sales of horror books is greater than sales of cookbook is 1.85% approx.

Answer:
im pretty sure number 3 is yes.
Step-by-step explanation:
15x-2 = 5x+3
subtract 3 from both sides which is now-
15x-5=5x
then now you subtract 15x from both sides which is now-
-5x= -10
now you divide both sides by -5 which will give you 2
i dont know for sure but hopefully this helped
