Me. i'll respect you forever! ( i'll give brainliest at the best) a) in a game, one gains 5 points for every won round and loses 3 points otherwise. after 20 rounds, mike had 68 points. how many round did he win? b) baby dragons have one head and two wings, adult dragons have 3 heads and four wings. in one dragon family, there are 25 heads and 36 wings. how many dragons are there in this family?

There are 4 babies and 7 adults 

B head=4x1=4   A heads=(3x7)=21     21+4=25 heads

B wings is 4x2=8  A  is wings(4x7)=28       28+8=36 wings

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.
