Answer : A
The word "increased" indicates a plus sign. The word "is equal" helps show us show that something is = to 15
One way in which to approach this problem would be to treat it as an equation of ratios and to cross multiply:
<span>[(4x + 15) / 5x)] = 1/2 could be written as:
4x + 15 1
----------- = ---
5x 2
Then 8x + 30 = 5x
3x = -30, and so x = -10 (answer). Be certain to check this answer through substitution!

The side length is six units.
A cube has three measurements: length, width, and height
All the measurements have to be the same.
This allows you to cube root.
The cube root of 216 is 6.
The side length of the cube is 6 units.
Check:
6 * 6 * 6 = 216.
It is correct, so our answer is proven to be correct.
7 x 500,000 = 3,500,000.
The towns are 3,500,000 units apart (I don't know what the cm were scale too, sorry.)
