Answer 1

Sorry, the equation is b = 10 + t

Answer 2

Lets plug the values given in 'A' in, and see what you get

Answer 3

So the numbers in A, under "b" are the only ones that is divisible by 10?

Answer 4

You have to plug both values for b and t in.
In the first case,
b = 20 while t = 2

Plug in:
b = 10 + t
20 = 10 + 2
Is it true?

Answer 5

No.. it is
20 = 10 x 2

Answer 6

My next choice would be C.

Answer 7

Your equation is : b= 10 + t or b = 10 x t?

Answer 8

b = 10 + t

Answer 9

Yes so that makes it invalid, now Choice C, Lets plug it in.

Answer 10

Now you have to check for all values.

Answer 11

b = 10 + t
12 = 10 + t
12 = 10 + 2 ✔

Answer 12

b = 10 + t
14 = 10 + t
14 = 10 + 4 ✔

b = 10 + t
14 = 10 + t
14 = 10 + 6 ✔

My final answer is C and I am confident in my answer. ✔
