Ok, so they are all balanced, so each side of the scale thing is equal to the other side.

A. 3 + x = 8
If we subtract 3 from 8, what’s left is 5 for x
x = 5

B. 2y = 12
Both y weights are equal, so dividing 12 by 2 says each y weight is 6.
y = 6

C. 4z = 11
All z weights are equal, so divide 11 by 4 to find the weight of z
z = 2.75

D. 3 4/5 + w = 13 4/5

Subtract 3 4/5 from 13 4/5 to find the weight of w
w = 10

Let me know if you have questions about this.

-9

Step-by-step explanation:

Given :-

A Arithmetic sequence -5 , -14 , -23 ...

And we need to find out the common difference of the Arithmetic sequence . The common difference of a Arithmetic sequence is the number which is added to a term to obtain the next term of the sequence . And it can be obtained by subtracting the consecutive terms.

Sequence :-

$:\implies$ -5 , -14 , -23
