the sun is 432,690 away and a penny is 1.52 mm in thickness
and 1.52 x 5 billion is 7,600,000,000 mm which is 4722.4 miles a year
<h2>f = -5</h2><h3></h3><h3>f(x) = 4x - 9</h3><h3>Add 9 to both sides</h3><h3>f(x) + 9 = 4x</h3><h3>Divide x from both sides</h3><h3>f + 9 = 4</h3><h3>Subtract 9 from both sides</h3><h3>f = -5</h3><h3></h3><h3><em>Please let me know if I am wrong.</em></h3>
Ratios that are equivalent to each other are considered equivalent ratios. For example, 2:6 is equal to 6:18
