Hey there! This is gonna actually be surprisingly simple even though it looks confusing!
Since the scale is perfectly balanced (it's completely flat because the weights are equal) you can use an = sign.
There are 3 cubes which weigh 9 ounces so 3 times 9 is 27 so on the left side you can put down a 27. Then there are 7 circles so so 7x can represent this. So that belongs on the left side as well SO for the left sides we can write this
27 + 7x = _______
Now for the right side. There are 5 cubes so 5 times 9 ounces is 45 so that belongs on the left. And then there is one cube so we can just right x. SO for the right side (combined with the other parts we know looks like this.
27 + 7x = 45 + x
NOW for the solving!
<span>27 + 7x = 45 + x
</span>subtract x from both sides
27 + 6x = 45
subtract 27 from both sides
6x = 18
then divide 6 from both sides
x = 3
So the circles are 3 ounces!!!!
I hope that helps! And feel free to ask me any questions!!

The after 29 minutes 38 seconds, Jane and Kinsley will be 47 miles apart if they are moving in the exact opposite directions.
<h3>What is distance?</h3>
A numerical representation of the distance between two items or locations called distance. A physical length or an approximation based on other considerations in physics or common usage can be referred to as distance.
Let's suppose the at time t they are 47 miles apart.
We know, distance = speed×time
(44+51)t = 47
t = 47/95
t = 0.494 hours
t = 29 minutes 38 seconds
Thus, the after 29 minutes 38 seconds, Jane and Kinsley will be 47 miles apart if they are moving in the exact opposite directions.

V = lhr
V ÷ lh = lhr ÷ lh
V/lh = r
r = V/lh
Just divide both sides by what you want removed, leaving behind r.
Final price = whole sale price+ 8% whole sale price
24.50 +(8/100 × 24.50)
24.50 + 196=$ 26.46
Answer:
The answer is 180
Step-by-step explanation:
So to start off you have to turn 20% into a decimal and that is .20.
Next you need to mutiply 225 and .20 and you will get 45 (that means it is $45 off)
Subtract 45 fro 225 and that is your answer.
You now pay $180 for the 20 foot extension ladder.
