We can set up a proportion since we know the ratio between the # of purple marbles and the # of green marbles.
A ratio is a way to compare two different values: for every 8 purple marbles there are 5 green marbles
<h2>

</h2><h2 /><h2>when we cross multiply, we get 5p = 240 </h2><h2>we divide both sides by 5 to isolate the variable </h2><h2 /><h3><u>There are 48 purple marbles </u></h3>
This is hard math is hard
M=c/at
Divide both sides by a and t to isolate m. Then the solution is just m=c/at
<span>90 + 35 = 125.
180 -125 = 55 degrees.
4.59^2 + 6.55^2 = 8^2
21.1 + 42.9= 64 inches</span>
