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.
Yw and pls mark me brainiest
We must find time by using the simple interest formula:
I = P x i x t
I is the interest
P is the total principal
i is the rate of interest per year
t is the total time in years
In this example, when we plug our known values in, our formula looks like this:
t =

t =

t = 4
So time (in years) would be 4 years.
Answer:
The range is is set of all second pairs (y-coordinates) while the domain is the set of first pairs(x-coordinates)
Step-by-step explanation:
~Hello There!~
Finding the perimeter simply means adding all the sides together.
31 + 81 + 31 + 81 = 224 cm
Yes, you are correct.
Hope This Helps You!
Good Luck :)
