x=25,y=15 Not to sure abt this answer but I think I got it
The answer is A) Right because the lengths 3 cm and 3 cm are obviously the same so it will form a right angle
X = small van capacity, y = larger van capacity
y = x + 6
2x + y = 57
now we sub in x + 6 for y
2x + x + 6 = 57
3x + 6 = 57
3x = 57 - 6
3x = 51
x = 51/3
x = 17
y = x + 6
y = 17 + 6
y = 23
small van (x) has 17 seats and large van (y) has 23 seats
ANSWER = 17.5% of 360 = 63
EXPLANATION:
Find 10% of 360 = 36
Then 5% of 360 = 18
Then 2.5% of 360 = 9
Add them together
so 17.5% of 360 = 63

and in case you recall your inverses, when f( g(x) ) = x, or g( f(x) ) = x, simply means, they're inverse of each other.
