4.5 inches multiplied by 1.5 feet equals 6.75 feet.
Answer:
P(A) = 86 / 265
P(B) = 39 / 153
P(C) = 243 / 326

2 163 80 83 326
Total 265 178 307 750
Computation:
P(A) = 86 / 265
P(B) = 39 / 153
P(C) = (163 + 80) / 326 = 243 / 326
Equal because when you turn it in to a mixed number it turns out to be 7 1/2 :) Hope this helps!
You can solve this via algebra, lets say the numbers are x and y.
x + y = 43 and x - y = 19
You can re-arrange one of the equations to get
x = 43 - y Then substitute this into the other equation, so instead of x you put this:
(43 - y) - y = 19
43 - 2y = 19
-2y = 19 - 43
-2y = -24
-y = -12
so y = 12
then you can do 43 - 12 = 31 to get both of the numbers.
so the numbers are 31 and 12
