3. Measure the length of MN to the nearest tenth of a centimeter. M 2 3 5 6 8 1.9 cm 6.9 cm C. d. 1.4 cm 6.4 cm b.

you have to put the graph on here with the question

step-by-step explanation:

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.

y=-2x0 is most likey your asnwer
