1. A sum of money is shared among Jessica, Amanda, and Beverly in the ration 8:9:3
astra-53 [7]

Answer:

$200

Step-by-step explanation:

Amanda       Beverly

     9         :       3

difference between Amanda and Beverly = 9 - 3 = 6 portions.

∴ value of 6 portions = $60

   value of 1 portion  =  $ 60 / 6

                                  = $10

Total no. of portions = 8 + 9 + 3 = 20

Total sum of money to be shared = value of 1 portion x Total no. of portions

                                                         = $10 x 20

                                                         = <u>$200</u>

Solving an Absolute Value Equation
Andre45 [30]

Answer:

Solution set = {-12, 12}

Step-by-step explanation:

Start by dividing both sides of the given equation by negative one, to get rid of the negative signs on both sides:

-\,|-x|=-\,12\\|-x|=12

Now we consider the two possible cases:

1) The expression inside the absolute value symbol is a positive number, then :

|-x|=-x\\

and replacing it in the equation, this becomes:

|-x|=12\\-x=12\\x=-12

which is our first answer.

2) The expression inside the absolute value symbol is a negative number, then :

|-x|=x\\

and replacing it in the equation, this becomes:

|-x|=12\\x=12

which is our second possible answer.

Then the set of solutions is: {-12, 12}

Consider the following triangle side lengths and determine if the triangle could exist. Justify your answer. Part A: 21,18,17 Pa
Misha Larkins [42]

Answer:

A yes, B no

Step-by-step explanation:

The triangle inequality states that the sum of any 2 sides of the triangle must be greater than the third side.

A Given 21, 18, 17 , then

21 + 18 = 39 > 17

21 + 17 = 38 > 18

18 + 17 = 35 > 21

Thus the triangle could exist

B Given 3, 12, 8 , then

3 + 12 = 9 > 8

3 + 8 = 11 < 12 ← fails the test

Thus the triangle does not exist
