I believe the easiest way to do this is to set up a proportion. We can also rephrase this to help. We know that 30 is 5% of the total. From here we can set up a proportion. 30/x = 5/100 3000 = 5x Cross multiply 600 = x Divide both sides by 5
600 should be the answer. To test the answer, do 30/600 and you should get 5% or .05.
Hope this helps! Be sure to message me if you have any questions!
Area is equal to width times length: A = w*l We know A <span>(48x^2+16x), l = 8x. Plugging into the equation: </span><span>(48x^2+16x) = 8x * w Divide both sides by 8x 6x + 2 = w
