O
A. 23+0;
O B. 7 +16
O C. 16-7;
O D. 7 + 136​

Answer 1

2 v - 129

Explanation:

Simplify the following:

v - 36 + v - 100 + 7

Grouping like terms, v - 36 + v - 100 + 7 = (v + v) + (-36 - 100 + 7):

(v + v) + (-36 - 100 + 7)

v + v = 2 v:

2 v + (-36 - 100 + 7)

-36 - 100 + 7 = 7 - (36 + 100):

2 v + 7 - (36 + 100)

| 1 | 0 | 0

+ | | 3 | 6

| 1 | 3 | 6:

2 v + (7 - 136)

7 - 136 = -(136 - 7):

2 v + -(136 - 7)

| | 2 | 16

| 1 | 3 | 6

- | | | 7

| 1 | 2 | 9:

Answer: 2 v - 129
