Suppose a mango cost x dollar and a apple cost y dollar
there will be an binary system of equation
8*x+3*y=18
3*x+5*y=14.5
so soultions have to x=48/31 y=16/31
Am not good at that much but let me try
Let x be the original position.
After the first play they gain 9 yards. The position can be represented by
x + 9
After the second play they lose 22 yards. The position can be represented by
x + 9 - 22 = x - 13
Therefore, in total they lost 13 yards.
Its D 15+15+15= 45 so there for it will be 45
17 tens can be said as 17 x 10
So 17 x 10 is 170
170 is in standard form
