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.
Answer:
Yes, Sally has enough money to buy 28 cans of soda.

Answer:
4 |x+7| divided by 3.
Step-by-step explanation:
This cannot be divided any further.
Equation - x = -3/10 + (10-1)
The original number is 9.3 because
x = -3/10 + (10-1)
x = -3/10 + 9
x = 9.3
