Given the literal equation ab/a+b = c , with b = –1 + a, what is the value of c if a = 5?
2 answers:
Answer:
Option A
Step-by-step explanation:
The given literal equation is
with b = ( a-1 )
We have to calculate the value of c when a = 5
Now we put b = ( a - 1 ) in literal equation
Now we have to calculate the value of c when a = 5
Option A is the answer.
The solution would
be like this for this specific problem:
ab/a+b = c
b = -1 + a
for c: <span>(5(-1 + 5))/(5 + (-1 +5)) </span><span>5(4)/ 5 + 4 </span><span>20 / 9 </span>
<span>The correct
answer between all the choices given is the first choice or letter A. I am
hoping that this answer has satisfied your query and it will be able to help
you in your endeavor, and if you would like, feel free to ask another question.</span>
