Is (10, 3) a solution to this system of inequalities?

y ≤ 3
y > x + 4

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

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.

answer: 2/13 chance i think ( ͡° ͜ʖ ͡°)( ͡° ͜ʖ ͡°)
