Let us say that the numbers are x and y. The given clues
are:
1. x – y = 16 (so
x is the larger number)
2. y / x = 5 / 7
rewriting eqtn 2 in terms of y:
y = (5/7) x
combining 1 and 2:
x – (5/7) x = 16
(2/7) x = 16
x = 56
y = (5/7) x = 40
So the two numbers are 56 and 40.
You would set it up: .5/100 = x/490 and then cross multiply .5 time 490 and 100 times x, and end up with: 245=100x. divide by 100, and get 2.45
9x^2-49
It equals:
<span>(<span><span>3x</span>+7</span>)</span><span>(<span><span>3x</span>−7</span><span>)
Hope this helps!

To find the volume of the recycling bin, you will use the formula for finding volume of a rectangular prism.
V = lwh
V = 12 x 512 x 612
V = 3760128 cubic meters
The answer is not given, but based in these numbers this is correct.
If it is 12 m x 5 m x 6 than the answer is 360 cubic meters
The ANSWERRRRRRR would be 32
