Question 1. -3 + v5 = 0
Work : -3 + 5v = 0
5v = 3 ( divide )
answer v = 3/5
Question 2. 1 - 7B = -20
work : -7b = -20 - 1
-7b = -21 ( divide )
answer b = 3
question 3 : -k - 5 = 0
work : -k = 5
answer : k = - 5
Question 4 : -1 + 8a = 129
work : 8a = 129 + 1
8a = 130 (divide )
answer a = 65/4
Answer:

Step-by-step explanation:

Answer:

Answer:
k = 7.3333333 ...
You can round accordingly of write the fraction form
Step-by-step explanation:
4/k = 6/11
6 ÷ 4 = 1.5
11 ÷ 1.5 = 7.3333333 ... (repeating)
4/7.333 = 6/11
