Answer:
W=1/z(A-9z)
Step-by-step explanation:
Use the distributive property to remove the bracket.
A=Wz+9z
Subtract 9z on both the sides.
A-9z=Wz
Divide by z on both the sides.
W=1/z(A-9z)
247/38=6.5. This tells us it will take 6.5 hours to drive 247 miles. Hope it helps.
Answer:
C. 28 = (2x - 1)(x)
Step-by-step explanation:
Given :
There is a rectangular swimming pool.
Width of swimming pool is x
Length is one less than twice the width
Area of the swimming pool is 28 sq ft.
To Find : Equation could be used to model the area of the swimming pool.
Solution:
Since we are given that Length is one less than twice the width.
And width is x (given)
So, length = 2x-1
Area of the swimming pool is 28 sq ft.
Now ,
Formula of area of rectangle : Length*Width
⇒28= (2x-1)(x)
So, equation used to model the area of the swimming pool: 28= (2x-1)(x)
Hence Option c is correct.
