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

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
