What are the values to choose from?
I think its a. but i could be wrong
You can obtain the a number for which they all divisors by calculating the least common multiple.
This way:
85 = 5*17*1
17=17*1
19=19*1
4=2^2 *1
2=2*1
The least common multiple is: 5*17*19*2^2 = 6,460.
Then 84, 17, 19, 4 and 2 are all divisors of 6,460.
Answer:
6
Step-by-step explanation:
C=9.2v + 21.2
76.4 = 9.2v + 21.2
76.4 - 21.2 = 9.2v
55.2 = 9.2v
v= 55.2 / 9.2 = 6
