Answer:

The propotional quantity to \frac{35}{80} is \frac{7}{16}

Step-by-step explanation:

We need to find quantity propotional to \frac{35}{80}

first, we simplify the expression

\frac{35}{80}

Since, the common factor in numerator and denominator is 5,

\frac{5\times 7}{5 \times 16}

cancel out the common factor

\frac{7}{16}

Hence, the propotional quantity to \frac{35}{80} is \frac{7}{16}

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:
after 7 minutes
19,600 feet
Step-by-step explanation:
Here's the "pencil and paper" solution:
The two altitude equations are ...
y = 41300 -3100x
y = 2800x
They can be solved by setting the expressions for y equal to each other.
2800x = 41300 -3100x
5900x = 41300
x = 41300/5900 = 7
y = 2800·7 = 19600
The planes will both be at 19,600 feet after 7 minutes.
