In Exercises 2 and 3, find the value of x that makes PQR ~JKL.

2. 4

3. 9

Step-by-step explanation:

2. 4 ~ 8

3 ~ x + 2

x + 1 ~ 10

8 / 4 = 2

2 (3) = x + 2

6 = x + 2

- 2     - 2

x = 4

2 (x + 1) = 10

/ 2           / 2

x + 1 = 5

   - 1   - 1

x = 4

3. 9 ~ 13.5

x + 1 ~ 15

13.5 / 9 = 1.5

1.5 (x + 1) = 15

/ 1.5         / 1.5

x + 1 = 10

  - 1    - 1

x = 9

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
