The two numbers are 2.4 and 1.5 respectively.
A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
Consider the numbers be: x and y
Given that sum of two decimal numbers is 3.9. Their difference is 0.9 and their product is 3.6
Then the system of equation;
x+y=3.9
x-y=0.9
Adding both the equation we get;
2x = 4.8
x = 2.4
Now for the value of y.
2.4+y=3.9
y=3.9 - 2.4
y = 1.5
Therefore, the two numbers are 2.4 and 1.5 respectively.

Answer:
He would pay $5.49.
Step-by-step explanation:
Edward paid $4.77 in sales tax on an item that cost $53 before tax.
Percentage of sales tax given on the item = × 100
= 0.09 × 100
= 9%
9% sales tax of an item that cost 61.00 = × 61
= 0.09 × 61
= $5.49
He would pay $5.49 in sales tax for an item that cost $61.00 before tax.
Answer:
The cost with tax is $66.49
Step-by-step explanation:
100% = 53
53 ÷ 100 = 0.53
4.77 ÷ 0.53 = 9% (sales tax)
100% = 61
109% = 61 + sales tax
61 x 1.09 = $66.49
