Answer:

1 is x=12

2 is x= 1/5

Step-by-step explanation:

For equation number 1 you just add 10 and 2, which is 12.

For equation number 2 you divide 2 by 10 and simplify it to 1/5. So x = 1/5

Answer:

First statement: 10 road workers take 5 days to complete a work, working 2 hours a day.

Let us calculate how many days 2 workers will need, if they were to work at the same pace (i.e. each working 2 hours a day). The workforce is now decreased to 2 divided by 10 = 1/5 (i.e. one-fifth).

Therefore proportionately, the time will increase to 5 days divided by 1/5, (i.e. 5 / (1/5) = 25 days.

We now know that 2 workers will need 25 days to finish the work, if they work for 2 hors a day.

Now the question is what will happen if the two people work 5 hours per day, instead of 2 hours per day?

The labor they put in has increased to 5 divided by 2 = 2.5 (i.e. 2 and half times).

Consequently, the time needed to finish the work will decrease to 25 divided by 2.5 (i.e. ( 25 / 2.5 ) = 10. days.

The answer : 10 Days.

If the distance covered by an object in time t is given by s(t)=t^2+5t , where s(t) is in meters and t is in seconds, what is th
alisha [4.7K]

Answer:

E. 44 meters

Step-by-step explanation:

The function that models the distance covered by the object is

s(t)=t^2+5t

where s(t) is in meters and t is in seconds.

The distance covered by the object after 1 second is

s(1)=1^2+5(1)=6m

The distance covered by the object after 1 second is

s(1)=5^2+5(5)=50m

The distance covered between 1 second and 5 seconds is

50-6=44m
