Answer :
We want to evaluate the expression
[tex]$$
1.64 \div (15 - 7) \times 2 - 9.
$$[/tex]
Let's go through the problem step by step.
1. First, calculate the difference inside the parentheses:
[tex]$$
15 - 7 = 8.
$$[/tex]
2. Next, divide [tex]$1.64$[/tex] by the result obtained in step 1:
[tex]$$
1.64 \div 8 = 0.205.
$$[/tex]
3. Then, multiply the quotient by [tex]$2$[/tex]:
[tex]$$
0.205 \times 2 = 0.41.
$$[/tex]
4. Finally, subtract [tex]$9$[/tex] from the product:
[tex]$$
0.41 - 9 = -8.59.
$$[/tex]
Thus, the final result of the given expression is
[tex]$$
-8.59.
