start inside the square root, replace X with -7.
-7 + 11 = 4
The number 4 comes out of the square root as 2.
Now there's a minus factor out there. Let's multiply this negative factor by 2 and get -2.
Now let's add -2 and -3.
Our output is -5.
Answer:
3 hours + 5hours = 8 hours ÷ 2 =
4 hours is your answer.
Step-by-step explanation:
If you have 2 people working and need to know how long it would take them to finish a job. Working together on the same job, you add each of their total hours to do the job alone,, 5 + 3 = 8, then divide the 8 by 2 people
equals 4 hours for 2 people on 1 job.
Answer
Cut out the shapes, and then multiply them.
Step-by-step explanation:
Since you don't provide the coordinates of the point W, I will help you in a general form anyway. In the Figure below is represented the segment that matches this problem. We have two endpoints U and V. So, by using the midpoint formula we may solve this problem:
Therefore:
So we know 
but we also must know 
Finally, knowing the points U and W we can find the endpoint V.
Answer:45 * t = 2.5 * (1-t)...the equation will have one solution.
Step-by-step explanation:
For this case, the first thing you should know is:
d: v * t
Where,
d: distance
v: speed
t: time
To go to school by bus we have:
d = 45 * t
To return from school we have:
d = 2.5 * (1-t)
how the distance is the same:45 * t = 2.5 * (1-t)
