Commutative Property of Multiplication
In a proportion there are letters assigned to represent various numbers. a, b, c, and d.
a, b, c, and d are 4 non-zero rational numbers that are terms of proportion.
a/b = c/d or a:b = c:d
a and d are the end terms or known as the extremes.
b and c are the middle terms or known as the means.
With this information, we can gather that the extremes of the following proportion are 3 and 60.
3/15 = 12/60 ; a/b = c/d
a = 3 ; b = 15 ; c = 12 ; d = 60
3 and 60 are the extremes
15 and 12 are the means
4.166 cans !
6*75 = 450 sq.ft
so approximately 4.166 cans will be required !
If you want to solve that put it in the formula to find the slope
M=
Y1-y2
---------
X1-x2
And plug that into slope int form with one of the points to find the y int/ b value and then your have ur equ
let's say that C is "x" units farther from B, that means that CB = x, and therefore AC = 1.5x.
