Answer: TRUE!
Variables ARE letters used in place of numbers absolutely
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
I would say 95/6 because you multiply 5 and 15 and turn it into an improper fractions
Answer:
2/35
Step-by-step explanation:
original equation:q+1/7=1/5
subtract both sides by 1/7
q=1/5-1/7
q=2/35
