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:
Pic 1: 
Pic 2: 
Step-by-step explanation:
<u>Picture 1:</u>
<u />
First, add the 2x and x together for 3x
Then add 3 to both sides of the equation
Finally, divide each side by 3.
<u>Picture 2:</u>
<u />
<u />
First, add 7x and x together for 8x
Then, minus 20 from both sides of the equation
Finally, divide each side by 8.
Answer:
improper
Step-by-step explanation:
a proper fraction is a fraction under 1 like 3/4
a mixed number is a whole number and fraction like 2 1/3
and a improper fraction is a fraction with a numerator greater the denominator
Answer:
The graph is shifted 1 unit right
The graph is shifted 2 units down
Step-by-step explanation:
We are given
Parent function as

New function as

we can also write as

We can see that
1 is subtracted to x-value
and 2 is added to y-value
So, f(x) is shifted right by 1 unit
and
f(x) is shifted up by 2 unit
