Answer:
x=9
Step-by-step explanation:
PQ + QR + RS = PS
2x-6 + 1 + x-4 = 18
Combine like terms
3x -9 = 18
Add 9 to each side
3x-9+9= 18-9
3x = 27
Divide by 3
3x/3 = 27/3
x = 9
Answer:
y^2/x^6
apply exponent rule:
x^-2/x^4=1/x^4-(-2)=y/y^-1 x^4 -(-2)
then you subtract 4-(-2)=6
y/x^6 y^-1
cancel out the common factor: y^-1 and you get
y^2

x^6
P = 3r + 2s --> P - 3r = 3r - 3r + 2s
2s = P - 3r --> 2s/2 = (P - 3r)/2
s = (P - 3r)/2
Answer:
12.41 minutes.
Step-by-step explanation:
It is given in the question that a plane can fly 725 miles per hour.
So, the plane goes 725 miles in 1 hour i.e. 60 minutes.
Now, we have to find the time the plane takes to fly 150 miles.
As the plane is flying at a constant rate, so we can use the unitary method to get the required time.
Therefore, the plane will take
minutes to fly 150 miles. (Answer)
