Select all expressions that complete the statement using the specified property. Commutative Property of Multiplication. 13.2 ×(x×1)= (1×x)×13.2 (x×1)×13.2 13.2×(1×x) (13.2×x)×1 13.2×x×1

but which class are u may know that first

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
