Answer:
598 books
Step-by-step explanation:
Let x be the number of books in the 3rd pile. We will have then:
1st pile: 2x + 10
2nd pile: 2x
3rd pile: x
3000 = (2x + 10) + (2x) + (x)
3000 = 5x + 10
3000 - 10 = 5x
2990 = 5x
2990/5 = x
x = 598 books in the third pile!
We can check that:
3000 = 2*598 + 10 + 2*598 + 598
3000 = 1196 + 10 + 1196 + 598
3000 = 3000 CHECK!
Answer:
Step-by-step explanation:
1. Relation - a set of ordered pairs
2. Vertical line test - a test used to determine if a graph is a function; states that a vertical line can only go through one point on the graph to be a function
3. Function - a relation in which for any given input value, there is only one output value
4. Output - value generated by a function when an input value is substituted into the function and evaluated
5. Ordered pair - a group of two numbers written in the form (x, y) where the x value represents a horizontal position and the y value represents a vertical position
6. Mapping Diagram - a table or diagram that represents a mathematical relation
7. Input - a value that is substituted in for the variable in a function in order to generate an output value

Hope that helped!
It’s probably 22 because 5 is on two sides and 11 is on two sides so 11 + 11+ 5+5 = 32
<span>Well 68/80 as a percent is 85 % .I got that by dividing 68 by 80 and them multiplying by 100. 100-85= 15. So therefore the dress decreased in price by 15%. </span>
