Answer:
169.6
Step-by-step explanation:
So
a be first term and d be common difference
- a+a+2d+a+4d+a+6d+a+9d=17
- 5a+21d=17--(1)
And
- a+d+a+3d+a+5d+a+7d+a+9d=15
- 5a+25d=15--(2)
Eq(1)-Eq(2)
Put in second one
- 5a+25d=15
- a+5d=3
- a+5/2=15
- a=15-5/2
- a=25/2
Answer:
Kind Note:
This question is incomplete. You need to provide the question in order to get the best answer on brainly. In this answer, I will tell you how many solutions are in this system of equations.
Step-by-step explanation:
This question involves the use of 'system of equations'.
3x - 2y = 44
- => (-3x + 3x) + (-7y - 2y) = (8 + 44)
- => -9y = 52
- => y = -52/9 (No further check required)
Since the y-intercept is valid, the system of equations has one solution.
Hence, this system of equations has one solution.
