At a concession stand, three hotdogs and two hamburgers cost 8.50, two hotdogs and three hamburgers cost 9.00. what is the cost of one hamburger and one hotdog?

so far i have:
x=hotdog
y-hamburger
3x+2y=8.50
2x+3y=9.00
for the life of me i cannot remember any of the steps past that. any would be awesome.

because its not ur topic and its not for is for homework not that.

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
