Answer:
x=25
Explanation:
Using the method of cross multiplication and division set up like so,
(100•4.5)/18 will give you 25.
4.5•100=450
450/18=25
160/4 = p/6
Cross-multiply the propportion:
160 x 6 = 4p
Divide each side by 4:
p = 40 x 6 = 240 pages
B= number of beakers which there are 450
t= number of test tubes
the answer is 1.46
