Solving multi - step equations
1.-5(5+5n)=-125
2.-1+8(-8x-3)=-281
3.-4(1-6a)=116

yes. we do proportions in probabilities.

entering that problem on the tube might get you an answer

nswer: a   y-axis

step-by-step explanation:

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.
