Sati [7]

Answer: Answers provided below in sequential order.



Step-by-step explanation: UV = 12(3)-1

(They said that x = 3)

UV = 35 (12*3-1)

70 = TV

TU = UV

8x + 11 = 12x - 1

-4x = 10

x = -10/4 or -5/2 (simplified)

TU = 8 (3) + 11

TU = 35 (24+11)

If a,b,c are in arithmetic sequence then a = ...​
andriy [413]

Answer:

If a, b and c are in arithmetic progression, that means that a + c = 2b. So a + b, a + c and b + c are also in arithmetic progression.

This might help.
