Answer:
x=12 but who knows maybe
Step-by-step explanation:
if we are trying to say those lines are equal length than surely the equations must be equal value otherwise they aren't equal so we can probably set them equal to each other and solve for x right? 2x+6=3x-6 subtract 6. 2x=3x-12. subtract 3x. -1x=-12. divide by -1 so x=12.
For this case, what we must do is calculate the speed of the runner.
We have then that the speed is given by:
Where,
d: distance
t: time
Substituting values we have:
Answer:
the runners unit rate is:
x = 150 did this help you?
So basically it takes 10 people to paint a whole building. Forget about the 5 days. That's just there to confuse you. You have to first find out how much of a building can one person paint so, 1/10. So that means that 7 people can paint 7/10 of a building in 5 days
54044.55 ÷ 100 = 540.4455
