Answer:
y = -5 and x = -17
Step-by-step explanation:
We want to solve these two equations,
x = 3y - 2
x = 5y + 8
We can see that they both equal x so we want make them equal to each other so,
→ 3y - 2 = 5y + 8
⇒ Subtract 5y from both sides to collect the 'y' terms
→ -2y - 2 = 8
⇒ Add 2 both sides to collect the numerical terms
→ -2y = 10
⇒ Divide both sides by -2 to isolate y
→ y = -5
Now that we have found the value of y we can substitute this value into one of the 2 equations we have to find the value of x
⇒ We know that y = -5 so lets substitute that into x = 3y - 2
→ x = 3 × -5 - 2
⇒ Simplify
→ x = -15 - 2
⇒ Simplify further
→ x = - 17
We want to find the speed of the hyper loop if it takes 11 minutes from Dubai to Abu Dhabi. We will find that the speed is 761.75 km/h
<h3>
Working with speeds.</h3>
Remember the relation:
speed = distance/time.
Here we know that the time is 11 minutes (the time in which the distance is traveled) and the distance will be the distance from Dubai to Abu Dhabi, which we can find online.
The distance is 139.4 km
Now, we know that:
1 hour = 60 minutes.
Using this we can write the time in hours.
11 min = (11 min/60min) hours = 0.183 hours
Now we can just compute the speed:
S = (139.4 km)/(0.183 h) = 761.75 km/h
