Equation: n+4=12-10
a number= n
Btw: n is negative two..
Greetings!
"<span>A machine produces 75 widgets an hour. How many widgets does it produce in 6 minutes?"...
An hour/60 minutes is ten times more than 6.
Therefore, we divide the amount per hour by ten:
75/10
=7.5
The machine produced 7.5 widgets /7 full widgets every six minutes.
Hope this helps.

Answer:
30
Step-by-step explanation:
you can turn it into 9>sqrt(n)>7 (you have to change the directions of the inequalities since 7>sqrt(n)>9 is just false since 7 is clearly smaller than 9)
81>n>49 since n can't be negative
50-80 works, getting you 30 numbers that work
