If tossing 1 head is 1/2, then you have to do 1/2^4 which is 1/2 × 1/2 × 1/2 × 1/2 (I imagine it as a tree diagram if that helps). 2^4 is 16, so your answer is b) 1/16. Hope this helps!
Answer:
yes Wyatt is very correct
First, you want to multiply both sides by 8, just to simplify things.
24x + (8/14) = 2x
From there, subtract 24x from both sides to get x on one side of the equation.
8/14 = -22x
Lastly, divide both sides of the equation by -22 to get x by itself
8/-308=x
Or
-2/77 = x
Answer:
b=8
Step-by-step explanation:
Let x represent number of boxes of cookies and y represent popcorn bags.
We have been given that Ava sold 10 boxes of cookies and 8 bags of popcorn and raised $102. We can represent this information in an equation as:
We are also told that Greg sold 4 boxes of cookies and 12 bags of popcorn and raised $98. We can represent this information in an equation as:
Now we will use substitution method to solve our system of equations.
Form equation (1), we will get:
Upon substituting this value in equation (2), we will get:
Therefore, each bag of popcorn costs $6.5.
