Answer:z=47
Step-by-step explanation:
You're doing this because if you have z-31=16 you have to + 31 to 16 which would give you 47 then that would be a one step equation
z-31=16
you would make a line between the equal sign so it is organized then plus 31 to sixteen then that would get you to 47
Answer:
5 or 3
Step-by-step explanation:
Answer:

Step-by-step explanation:
You don't know the number, so you replace it with x.
Since it is one third of x, you multiply x by 
Then you subtract 5 from the whole thing: 
It's unlikely that it the dimensions are either 14 and 1 in front of the x or 6 and 1 for the 6, but this is math, so you never know. I would try 7 and 2 and 3 and 2 and see what comes of it.
(7x 2)(2x 3 ) That looks promising. We'll put the 3 with the 2x. That leaves us with the signs. We need 17 to be minus
(7x 2)(2x - 3) that gives you - 21 x So the 2 with the seven has to be plus.
(7x + 2)(2x - 3) should be the the factored answer.
7x + 2 = 0 has no meaning. Measurements cannot be minus.
2x - 3 = 0
2x = 3
x = 3/2
If there are choices, please list them. That's as far as is possible.
