The answer is eight
Two piano lessons a week means you just multiply two by the number of weeks
Hi there!
In order to answer your question you’ll need to write an equation in which “X” would be the number of containers you need to sell :
4X - 28 = 20
This equation means that each container you sell gives you $4, you also need to subtract $28 because that’s the cost for making the cookies and the equation is equal to 20 because you want to make a $20 profit.
Now that your equation in written down, you can solve it by isolating “X” :
4X - 28 = 20
Add 28 on each side of the equation → 20 + 28 = 48
4X = 48
Divide each side of the equation by 4 → 48 ÷ 4 = 12
X = 12
Your answer is D): In order to earn a $20 profit, you need to sell 12 containers.
There you go! I really hope this helped, if there’s anything just let me know! ☻
Answer:
i meant 7 bc it is isosceles.
Step-by-step explanation:
First lets start by making the denominators the same. I multiplied the 4 by 5 and 10 by 2.
-25/20 = x -14/20
Add 14/20 on both sides (do the opposite to cancel out and whatever you do to one side you need to do to the other.
You should get -11/20 = x
