Answer:
u=0
Step-by-step explanation:
For this case, the first thing we must do is define variables.
We have then:
x: number of hours
y: amount of movie posters
The equation modeling the problem for this case is given by:
Therefore, for 1265 posters we have:
From here, we clear the number of hours.
We have then:
Answer:
an equation to find the number of hours it takes the machine to print 1265 posters is:
The number of hours is:
If someone covers 4 laps in 12 minutes, he would be able to cover 1 lap in 3 minutes if that was the question. The question isn’t really clear.
Answer:
9
Step-by-step explanation:
12^2+x^2=(x+6)^2
144+x^2=x^2+12x+36
12x=108
x=9
