Answer: 40
Step-by-step explanation:
Let the two numbers be a and b.
Therefore,
a - b = 3 ....... i
a + b = 13 ....... ii
From equation I, a = 3 + b
Put a = 3+b into equation ii
a + b = 13
3 + b + b = 13
3 + 2b = 13
2b = 13 - 3
2b = 10
b = 10/2
b = 5
Since a = 3 + b
a = 3 + 5
a = 8
The product of the numbers will be:
= 8 × 5
= 40
The answer to this equation would be 7/20. Hope this helps! :D

Answer: 3.5 gallons
Step-by-step explanation:
From the question, we are told that Chanasia has 8.75 gallons of paint and that she wants to use 2/5 of the paint to paint her living room.
The gallons of paint that Chanasia will use be gotten by multiplying 2/5 by 8.75 gallons. This will be:
= 2/5 × 8.75 gallons
= 0.4 × 8.75 gallons
= 3.5 gallons.
This means that Chanasia will use 3.5 gallons to paint her living room
