Answer:
87.5 %
Step-by-step explanation:
Set up a ratio:
7/8 = x/100
Cross multiply to solve for x:
8x = 700
x = 87.5
If you would like to solve 7x - (25x^2 + 12x), you can do this using the following steps:
7x - (25x^2 + 12x<span>) = 7x - 25x^2 - 12x = - 25x^2 - 5x
</span>
The correct result would be <span>- 25x^2 - 5x.</span>
