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
This problem is an example of an arithmetic series.
The common difference of the second term (15) with the first term (9) and the third term (21) with the second term (15) [15-9=6; 21-15=6] is 6.
The formula for solving this is:
An= A1 +(n-1)*d where An is the nth term, A1 is the first term, n is the number of terms and d is the common difference.
An=9+ (31-1)*6 = 189
The answer is 189.
3936/9=440 if that is what you meant
Answer:
The dimensions of the scaled rectangle are
of length by
of width
Step-by-step explanation:
we know that
The scale factor is equal to 
Remember that

The scale factor is less than 1
so
the dilation is a reduction
To find the dimensions of the scaled rectangle multiply the dimensions of the original rectangle by the scale factor
