Carter is selling his bike. His research shows that the bike has a current value of $90, which is 45% of the amount Carter paid

GaryK [48]

Carter paid $200 for the bike.

Step-by-step explanation:

Given,

Current value of bike = $90

This represent 45% of the original amount Carter paid for bike.

Let,

x represent the original amount of bike.

45% of x = 90

$\frac{45}{100}x=90\\\\0.45x=90$

Dividing both sides by 0.45

$\frac{0.45x}{0.45}=\frac{90}{0.45}\\x=200$

Carter paid $200 for the bike.

Simplify the problem

Natasha2012 [34]

$\frac{6}{10x^2} \div \frac{6}{10x^3-60x^2} = \frac{6}{10x^2} \cdot \frac{10x^3-60x^2}{6} =\frac{1}{10x^2} \cdot \frac{10x^2(x-6)}{1} =x-6$
