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!!

Answer:
A: 500 square feet
Step-by-step explanation:
A: First you have to draw a grid.
You plot the points A,B, and C.
The fourth point would be -5,25 because it matches with the points.
You make a rectangle out of those points
Points AB is 2 feet. Since the interval I used was 5 I would multiply 2 by 5 to get 10.
Then I would find Points BC which is 10 feet. Again multiply it by 5 to get 50.
50 x 10 is 500.
B: Jenna has to reflect over the y-axis. This is because the y-axis is between Quadrants II and I. When reflecting over the y-axis the y-coordinate stays the same but the x-coordinate switches to it's opposite. Basically the x-coordinate is negative in Quadrant II, but in when reflecting over the y-axis the x-coordinate would change to a positive in Quadrant I. So if the point in Quadrant II looks like this: (-X,Y) then when reflecting over the y-axis to Quadrant I would look like this: (X,Y).
Answer:
A. 
B.
C. 
Step-by-step explanation:
A.
There are 52/4 diamonds in the deck and 4 '5's in the dech of cards
52/4 = 13 + 4 = 17
Therefore, you have a chance of drawing one of those cards.
B.
There are 13 hearts in the deck and 4 jacks. Therefore, your odds are the same :
C.
There are 4 jacks in a deck of cards and 4 '8's in a deck of cards
Therefore your probability is 
which simplifies to
