Walter wants to solve the given system of linear equations. X+ 2y = 9
6x - y = 2
His method is to replace the second equation with an equivalent form so that he can eliminate one of the variables by adding the equations tog
rewrites the system of equations as follows:
x + 2y = 9
12x - 2y =
What number should go in the blank space, in order for this system of equations to produce the same solution as the original system?

You paid 28.00 for 8 gallons of gasoline. how much would you pay for 15 gallons of gasoline?

If x+y+z=0 what is the value of [tex] {x}^{3} + {y}^{3} + {z}^{3} [/tex]

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
