Jason is participating in a walkathon. he writes the equation m=2d+50 to represent the amount of money m(money) he collects from each sponsor for walking d ( distance) kilometers. What number represents the rate of change?

the answer is: the length is 5/6 yards.

give me a or a 5 star rating if this is correct!

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.

i am so sorry , i have no idea but i want points so i won't be a beginner anymore

3x-x+2=4 i think that's is the answer, and i hope it you
