Find the 10th term in the following arithmetic sequence if the constant being added is -12
Step-by-step explanation:
20 - 12 = 8
8 - 12 = -4
-4 - 12 = -16
So the sequence will be
20; 8; -4; -16
an = 20 - 12(n - 1)
a10 = 20 - 12(10 - 1) = -88
Answer:
x = 145
Step-by-step explanation:
The reason being is because 145 is vertical to x and they are congruent so it is 145.
Answer:
6.7

15x = 60 + 6x
9x = 60
x = 6.7
