    Finding the Maximum Seats of Two Vans Using Linear Algebra

    x=33 x+y=71 33+y=71 -33 -33 y=38 is there another step??

    Finding the Maximum Seats of Two Vans Using Linear Algebra

    then x=33 then back to the situation where the smaller van(x) makes two trips and the question is trying to figure out what's the number of seats on the larger van. IS THERE ANOTHER STEP BECAUSE WHEN I INPUTTED 33 AS THE ANSWER IT WAS INCORRECT. A MORE RECENT QUESTION LIKE THIS ONE IS...

    Linear algebra and seats in a van

    Homework Statement A Company use two vans from 7-9am. ONE van has 9 more seat than the other. The smaller van makes two trips, and the larger van make 1 trip? The maximum seats of both vans that was given would be 69. Let x be the seats of small van and y be the seat of the larger van...

    Finding the Maximum Seats of Two Vans Using Linear Algebra

    y=x+5 71=x+y y=x+5 71=x+x+5 71=x2+5 -5 -5 66=x2 8.12=x IS THIS STILL WRONG?... DO I NEED TO INCORPORATE "The smaller van makes two trips, larger 1 trip".

    Finding the Maximum Seats of Two Vans Using Linear Algebra

    y=x+5 71=x+y ------------ y=x+5 -y=x-71 ------------ 0=x+5 0=x-71 -5-+71=76 ------------- this is wrong is it y=x+5 71=x+y ---------------------- -5=x+-y 71=x+y 66=x CORRECT IT PLease

    Finding the Maximum Seats of Two Vans Using Linear Algebra

    would it be x+y=71 because x=the smaller van and y= the larger van...put them together it has a seat of 71 AND if that's the case what's after this y=x+5 71=x+y

    Finding Groundspeed Using Linear Equations

    why do i have to use 100mph, and a 10mph tailwind? It wasn't given to the original problem.

    Finding Groundspeed Using Linear Equations

    6(x-y)=2400 6(440-y)=2400 2640-6y=2400 -6y=-240 y=40 well i know that: x is the max speed of the plane :440 y is the speed of the wind:40 if i divide it its: 11...is that the answer?

    Finding Groundspeed Using Linear Equations

    opps my mistake. 6(x-y)=2400 6(480-y)=2400 2880-6y=2400 -6y=-480 y=80 is this right. So is this the answer if their no wind for the plane or is there another step to it?

    Finding Groundspeed Using Linear Equations

    So would it rate x time= distance 6(x-y)=2400 against the wind 5(x+y)=2400 with the wind 6x-6y=2400 x-y=400 y=400-x ------------------------- 5x+5y=2400 x+y=480 x-(400-x)=480 2x-400=480 2x=880 x=440 --------------------------- 6(x-y)=2400 6(480-y)=2400 2880+2y=2400 2y=-480...
