Answer:

KJ = 60

Step-by-step explanation:

In order to find the length of KJ we must find the value of x

Perpendicular bisectors split lines into two EQUAL parts.

If GJ is bisected then the two parts that make it up are equal to each other.

In other words GK = KJ

If GK = 2x + 10 and KJ = 3x - 15 then

2x + 10 = 3x -15

Solve for x

2x + 10 = 3x -15

Subtract 2x from both sides

10 = x - 15

Add 15 to both sides

x = 25

Now to find KJ we simply plug in the value of x into KJ's given expression

Expression given: 3x - 15

x = 25

KJ = 3(25) - 15

Multiply 3 and 25

KJ = 75 - 15

Subtract

KJ = 60

Given,

  • HK is the perpendicular bisector of GJ. So, <u>GK = KJ</u>.
  • GK = 2x + 10
  • KJ = 3x - 15

_______________

Find KJ .

_______________

First find the value of x

\sf \: GK \:  = KJ \\\sf 2x + 10 = 3x - 15 \\\sf 2x - 3x =  - 15 - 10 \\ \sf - x =  - 25 \\  \sf \: -  >   \boxed{\bf \: x = 25}

Now, find the value of KJ.

\sf3x - 15 \\  \sf= 3(25) - 15 \\  \sf=7 5 - 15 \\     = \boxed{\bf \: 60}

-> The value of KJ is <u>6</u><u>0</u><u>.</u>

_______________

Hope it helps.

Dana and Monique are dog groomers. Dana’s workday is 10 hours and Monique’s workday is 8 hours. Dana and Monique each work 40 ho
Lana71 [14]

Answer:

$127.50

Step-by-step explanation:

To answer this you will need to figure out how many days each person is working each week based on their number of hours and how many hours they work.  Use this to determine the number of dogs groomed and then multiply by the hourly rate.

Dana works 4 days (40/10) and Monique works 5 days (40/8).

Dana:  15 dogs per day x 4 days a week x $12.75 per dog = $765 a week.

Monique: 10 dogs per day x 5 days a week x $12.75 per dog = $637.50 a week.

765 - 637.50 = $127.50.

The difference is $127.50.
