Moving at a constant rate, a race car travels 242 miles in 2 hours and 726 miles in 6 hours. Which equation represents the relationship between the number of hours (x) and the distance the race car travels (y)?

my guess is

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.

it's possible to build a triangle with side lengths of 3, 3, and 9.- true ( b.)

the answer is 6

hope this !
