Solve it by Substitution
1 answer:
30 in each bus. 17 in each van
To solve this problem, we first have to create a system of equations. After that, you set the equations equal to each other, and use that to simplify and find the value of one variable. Once that is found that answer can be plugged into one of the two original equations to find the other variable.

Answer:
S12 for geometric series: (-7.5) + 15 + (-30) + ... would be: 10237.5
Step-by-step explanation:
Given the sequence to find the sum up-to 12 terms
As we know that
A geometric sequence has a constant ratio 'r' and is defined by
∵
Thus, S12 for geometric series: (-7.5) + 15 + (-30) + ... would be: 10237.5
