Who came up wit the first one?!? Nah that’s to much!!
Answer is 6(c) + 50
Step by step
We know the following
6 months cable multiplied by “c” dollars per month plus $50 one time fee
6 (c) + $50
We multiply 6 months times the unknown “c” per month. Then we add the one time fee.
The other three options multiply $50 by 6 months, by 2 and by “c”, therefore not correct.
Divide 50 by 2
50/2=25
remember 2
divide 25 by 5
25/5=5
5 is prime
answe ris 2 times 5 times 5
Answer:
Here we can go for trial and error,
Taking x=6
So equation will be 6*6-18 which gives 18
and is not equal to 54
So it's, not 6
Trying 12
6*12-18
Which is 54 and so correct answer is x=12
