<u><em>Answer: A. -14. x=-14 and -14=x. *The answer should be the negative sign.*</em></u>

Step-by-step explanation:

subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

switch sides of an equation.

x+19=5

subtract by 19 both sides of an equation.

x+19-19=5-19

simplify.

19-5=14

x=-14 and -14=x

Hope this helps!

Thanks!

Have a great day!

A fruit market equally divided 80 red apples into 8 containers, and equally divided 54 green apples into 6 containers. Natalie b

Goryan [66]

Answer:

10 + 9 = n

19 apples

Step-by-step explanation:

80 ÷ 8 = y and 56 ÷ 6 = a

n = y + a

80 ÷ 8 × 8 = y × 8

80 = 8y

80 ÷ 8 = 8y ÷ 8

y = 10

54 ÷ 6 = a

54 ÷ 6 × 6 = a × 6

6a = 54

6a ÷ 6 = 54 ÷ 6

a = 9

10 + 9 = n

19 = n

Since we know that triangle inequality theorem states that sum of any two sides of a triangle must be greater than third side.

Now let us see if it is true for our given side lengths.

$10.6+5.6>4.0$

$16.2>4.0$

Now let us try with another pair.

$5.6+4.0>10.6$

$9.6$

We can see that sum of 5.6 and 4 is less than 10.6. Therefore, 10.6 cm, 5.6 cm and 4.0 cm can not be side lengths of a triangle.

cricket20 [7]

Answer:

0.714 ; 0.556 ; (A1 n A2 n A3) = 0

Step-by-step explanation:

Given that :

P(oil) = 0.35

P(filter) = 0.45

P(oil n filter) = 0.25

P(filter | Oil) = P(oil n filter) / P(oil)

P(filter | Oil) = 0.25 / 0.35 = 0.714

11)

P(Oil | filter) = P(oil n filter) / P(filter)

P(Oil | filter ) = 0.25 / 0.45 = 0.556

Number of red aces = 2

Queen or king = 4 + 4 = 8

Number on card greater than 3 and less than 8 = {4,5,6,7} = 4 card ; for 4 suits = 4 * 4 = 16

Total number of cards in deck = 52

Choosing without replacement :

Hence,

A1 = 2 / 52

A2 = 8 / 51

A3 = 16 / 50

(A1 n A2 n A3) ;this means card common to all three events.

However, (A1 n A2 n A3) = 0 because ;

1.) No red ace card is greater than 3 and less than 8.

11.) An ace card can neither be a king nor a queen
