Answer:
-6a-48
Step-by-step explanation:
The value of the expression, that is, 20.5 – (2 * 8.1) is 4.3
We have been given the expression 20.5 – (2 * 8.1).
To solve this problem we apply BODMAS rule, where each letter stands for
B = Bracket
O = of
D = Divide
M = multiply
A = Addition
S = Subtraction
When any equation is given where there is more than one operation, we solve them according to the BODMAS rule which tells us to solve the order of operation to be followed while solving expression in mathematics.
Now solving the expression we get,
= 20.5 – (2*8.1)
First solve the bracket expression
= 20.5 – 16.2
= 4.3
Hence the answer for the expression is 4.3

Not sure if this is for algebra but this is the algebraic solution.
1. 5x + 1y = 25 (x meaning number of nickels) (y meaning number of pennies)
so 3 solutions could be, 5 nickels and 0 pennies, 4 nickels and 5 pennies, 3 nickels and 10 pennies.
2. First calculate how many days till the end of October, (31-14)= 17 days. then add 30 days for the entire month of November. Then add the 5 days that occurred in December. This will leave you with a total of 52 days.
Given: F = {(0, 1), (2, 4), (4, 6), (6, 8)} and G = {(2, 5), (4, 7), (5, 8), (6, 9), (7, 5)} Find the common domain of F and G.
