M is the midpoint of YZ. If YM = x + 3, and YZ = 3x -1, find MZ
Elenna [48]
2(x+3)= 3x-1
2x+6=3x-1
X=7
Therefore
YM = 7+3= 10
And by definition of midpoint YM=MZ so MZ=10

The ratio of two numbers is 7 to 5. The sum of the numbers is 24. What are the numbers?
Kipish [7]

Answer:

14 and 10

Step-by-step explanation:

The ratio of the 2 numbers = 7x : 5x

The sum of the 2 numbers is 24, hence

7x + 5x = 24

12x = 24 ( divide both sides by 12 )

x = 2

7x = 7 × 2 = 14

5x = 5 × 2 = 10

Thus the numbers are 14 and 10

12. Linda walks through a road. If her walking speed increases from 1 m/s to 1.5 m/s, she will complete the walk 200 s earlier.
Katen [24]

Answer:

<u>600 meters</u>

Step-by-step explanation:

<u>Case 1 : Speed of 1 m/s</u>

  • d = v * t
  • d = 1 * t
  • d = t       [Equation 1]

<u>Case 2 : Speed of 1.5 m/s</u>

  • d = v * t
  • d = 1.5 * (t - 200)
  • d = 1.5t - 300 [Equation 2]

As distance in both cases is the same, equate the values of d from both equations.

  • t = 1.5t - 300
  • 0.5t = 300
  • t = 300 * 2
  • <u>t = 600 s</u>

Now, put the value of t in <u>Equation 1</u> to find d.

  • d = <u>600 meters</u>
