Answer:
46
Step-by-step explanation:
We know S(n) = n/2 [ 2a + (n-1)d ]
Here, n = 25
a = -7
d = -2-(-7) = -2+7 = 5
Substitute their values,
S(25) = 25/2 [2(-7) + (25-1)5 ]
S(25) = 25/2 [-14 + 120 ]
S(25) = 25/2 [106 ]
S(25) = 25 [ 53 ]
S(25) = 1325
In short, Your Answer would be 1325
Hope this helps!
Answer:
1/4, 2/6, 4/10
Step-by-step explanation:
1/4 = .25
2/6 = .333...
4/10 = .4
Given:
Consider the below figure attached with this question.
To find:
The solution to this linear system.
Solution:
From the below graph it is clear that both lines intersect each other at point (2,3).
Here,
x-coordinate = 2
y-coordinate = 3
Therefore, the solution to the given system is (2,3).
Hence, the required answer for first blank is 2 and for second blank is 3.
