Answer:

  • 6
  • 1/15
  • 13/15

Step-by-step explanation:

The fill-in for the first box is found by counting spaces between 0 and 2/5. There are 6 of them.

__

Since 6 spaces = 2/5, the value of 1 space is 1/6 of 2/5. We must multiply 2/5 by 1/6 to find the value of 1 space:

  1 space = (2/5)(1/6) = 2/30 = 1/15

This is the number that goes in the second box.

__

To find the value of x, count all the spaces. There are 13, so the value of x is 13 times the value of 1 space:

  x = 13(1/15) = 13/15

This is the number that goes in the last box.

Which of the following is an extraneous solution of √4x+41 = x+5?
dolphi86 [110]

Answer:

x=-8

Step-by-step explanation:

on squaring both sides

either x-2=0  or  x+8=0

either x=2 or x=-8

Putting x=2 in original equation, we get

7=7 hence, it is not an extraneous solution

Putting x=-8 in original equation

i.e. 3=-3

Hence, x=-8 is an extraneous solution (since it doesn't satisfy the original equation)

7) Line Segment PR is 5 ft. Find the length of Line Segment PQ and QR. (Hint: use the segment addition postulate.)
Ghella [55]

Answer:

PQ = 1 ft

QR = 4 ft

Step-by-step explanation:

From the picture attached,

Segment PR has been divided into two parts by a point Q.

Length of segment PR = 5 feet

Length of segment PQ = (15x - 2) ft

Length of segment QR = (5x + 3) ft

Since, PR = PQ + QR

5 = (15x - 2) + (5x + 3)

5 = 20x + 1

20x = 4

x = \frac{4}{20}

x = 0.2

PQ = 15x - 2

     = 15(0.2) - 2

     = 3 - 2

     = 1 ft

QR = 5x + 3

     = 5(0.2) + 3

     = 1 + 3

     = 4 ft
