Now Steve, you can tap these into your calculator one by one,
get all the quotients, and mark the ones that are 4.2, all in about
3 minutes.
There are three (3) of them in the list.
One of them is 'C'. 27.3 ÷ 6.5 = 4.2
Now pick up your calculator and find the other two. You can do it !
Hello from MrBillDoesMath!
Answer:
b = 0.6
Discussion:
The question can be written as
b - 7.4 = -6.8 => (now add 7.4 to each side)
b - 7.4 + 7.4 = -6.8 + 7.4 => ( note: -7.4 + 7.4 = 0)
b = 0.6
Thank you,
MrB
