I attached a photo of my work below. I used substitution to get an answer of 2.67 or 8/3.
Answer:
x=6÷5 this is answer we can also divide it in decimals also as 1.2
A. 7sr10-2sr3-3sr10+sr3
70sr-6sr-30sr+3sr
37sr
B. 192sr
C. sr12/27unless it is sr * 12/27 but you need to round because its too long.
Answer:
The Pythagorean Theorem gives us a2 + b2 = c2 for a right triangle, where c is the hypotenuse and a and b are the smaller sides.
Answer:
0.26 minutes
Step-by-step explanation:
So if you want to solve this, you need to make all the units the same first. What you first need to work on is the rate, since what it is asking is minutes given distance in feet.
We know that there are:
5280 ft in a mile
60 minutes in an hour
We then convert the rate knowing this:
![\dfrac{174\:miles}{4\:hours}\times\dfrac{5280ft}{1\:mile}\times\dfrac{1hour}{60\:minutes} = \dfrac{918,720ft}{240\:minutes} = \dfrac{3828\:feet}{1 minute}](https://tex.z-dn.net/?f=%5Cdfrac%7B174%5C%3Amiles%7D%7B4%5C%3Ahours%7D%5Ctimes%5Cdfrac%7B5280ft%7D%7B1%5C%3Amile%7D%5Ctimes%5Cdfrac%7B1hour%7D%7B60%5C%3Aminutes%7D%20%3D%20%5Cdfrac%7B918%2C720ft%7D%7B240%5C%3Aminutes%7D%20%3D%20%5Cdfrac%7B3828%5C%3Afeet%7D%7B1%20minute%7D)
In short, the car is traveling 3,828 ft every minute.
To determine how many minutes it will take for the car to travel just remember that:
![speed=\dfrac{distance\:travelled}{time}\;\rightarrow\;time=\dfrac{distance\;travelled}{speed}](https://tex.z-dn.net/?f=speed%3D%5Cdfrac%7Bdistance%5C%3Atravelled%7D%7Btime%7D%5C%3B%5Crightarrow%5C%3Btime%3D%5Cdfrac%7Bdistance%5C%3Btravelled%7D%7Bspeed%7D)
Now we plug in what we know and solve what we don't know:
![time=\dfrac{1000feet}{\dfrac{3828ft}{1minute}}\;\rightarrow\;1000ft\times\dfrac{1\:minute}{3828ft}=0.26\:minutes](https://tex.z-dn.net/?f=time%3D%5Cdfrac%7B1000feet%7D%7B%5Cdfrac%7B3828ft%7D%7B1minute%7D%7D%5C%3B%5Crightarrow%5C%3B1000ft%5Ctimes%5Cdfrac%7B1%5C%3Aminute%7D%7B3828ft%7D%3D0.26%5C%3Aminutes)
