Answer:

the number of hours taken is 2

Step-by-step explanation:

The computation of the number of hours taken is shown below:

As we know that

Distance = travel time × speed

The Guillermo to catch Dorabella be t = T

So the equations would be

9T = 4 + 7T

9T - 7T = 4

2T = 4

T = 2 hours

hence, the number of hours taken is 2

CL 2-107. Solve for w(show work): 6w - 5 + 8w - 2w - 3 = 9w - 24​
jekas [21]

Answer:

w = -16/3

Step-by-step explanation:

6w - 5 + 8w - 2w - 3 = 9w - 24​

Combine like terms

12w -8 = 9w -24

Subtract 9w from each side

12w -9w -8 = 9w -9w -24

3w -8 = -24

Add 8 to each side

3w-8+8 = -24+8

3w = -16

Divide each side by 3

3w/3 = -16/3

w = -16/3

In a rectangle, the length is 7 m less than three times the width and the area is 111 m. Approximate the dimensions to the neare
nikklg [1K]

Answer:

The dimensions are 7.4m by 15.1 m (to the nearest tenth).

Step-by-step explanation:

Area = length * width

If the width = x then the length = 3x - 7 so

Area x(3x - 7) = 111

3x^2 - 7x - 111 = 0

Using the quadratic formula:

x  = [ -(-7) +/- √((-7)^2 - 4*3*-111)] / (2*3)

x =  7.36, -5.03.

The width must be positive s it is 7.36 m.

The length = 3(7.36) - 7

= 15.08 m.
