Use properties of operations to enter an expression equivalent to the sum of the expressions 4g + 5) and
5(49 - 3). Simplify your answer as much as possible.
49 + 5) +5049 - 3) =

80%

step-by-step explanation:

a reflection across the x axis and a 90 degree rotation left and right.

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.
