Answer:
x=6
Step-by-step explanation:
The angles are alternate exterior angles, which are equal
19x-4 = 110
Add 4 to each side
19x -4+4 = 110+4
19x = 114
Divide by 19
19x/19 = 114/19
x=6
Answer:
Step-by-step explanation:
First sequence : 10,9.5,9,8.5,...
Let's see the difference between 2 numbers :
10 - 9.5 = 0.5
9.5 - 9 = 0.5
9 - 8.5 - 0.5
So on and so on. So, the common difference between these numbers are 0.5
Next sequence : 200,100,50,25, ...
We see, to get from one number to another, we divide it by 2 / multiply it by 1/2.
200 x 1/2 = 100
100 x 1/2 = 50
50 x 1/2 = 25
So on and so on. So, the common ratio of these numbers are 1/2.
The constant of proportionality is 13
50 would be a good choice of answer
