First you foil so you would get
0.5r+1.375=3
Then you subtract the 1.375 to the 3
0.5r=3-1.375
0.5r=2.375
Now to find r you need to divide by 0.5
r=2.375/0.5
You have to calculate the median and which the numbers all
I think the answer is between the 8 and the 10
If we let p and t be the masses of the paper and textbook, respectively, the equations that would best represent the given in this item are:
(1) 20p + 9t = 44.4
(2) (20 + 5)p + (9 + 1)t = 51
The values of p and t from the equation are 0.6 and 3.6, respectively. Thus, each paperback weighs 0.6 pounds and each textbook weighs 3.6 pounds.
