The frequency polygon
We have:
First, we calculate the midpoint of each class
Lastly, we plot the midpoint against the frequency of students (see attachment)
Hello!
Solve for x:
4(2x+25)=20
Distribute the 4 to the numbers inside the parenthesis.
8x + 100 = 20
Subtract 100 from both sides of the equation to get 8x by itself.
8x = -80
Divide both sides by 8
x = -10
Answer:
3/10
Step-by-step explanation:
To find how much remains, you need to find 1/2 of 3/5 which is 1/2 * 3/5. To multiply the two fractions, multiply the two numerators and multiply the two denominators to get 3/10. Thus, 3/10 of the candy bar remains.
Hope this helps :)

Answer: $20
Step-by-step explanation:
Let 'x' be the cost of a ticket at Haynes
Let 'y' be the cost of a ticket at Valley
Since the total cost from both schools are the same, we can write it as:
Since the cost of tickets at Valley was $5 less than Haynes, we can write it as:
Now we have two equations, we can use to substitute into the other expression:
we substitute y in this equation with the other equation
Therefore the cost of the ticket at Haynes is $20 and the cost of the ticket at Valley is $15.
