Answer:

30 and 6

Step-by-step explanation:

Given that R is the midpoint of QS , then

RS = QR , that is

5x = 3x + 6 ( subtract 3x from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Then

QS = QR + RS

     = 3x + 6 + 5x

     = 8x + 6

     = 8(3) + 6

     = 24 + 6

     = 30

------------------------------------------------------------------

Similarly

QR = RS , that is

6x - 9 = 2x - 1 ( subtract 2x from both sides )

4x - 9 = - 1 ( add 9 to both sides )

4x = 8 ( divide both sides by 4 )

x = 2

Then

QS = QR + RS

      = 6x - 9 + 2x - 1

      = 8x - 10

      = 8(2) - 10

      = 16 - 10

      = 6

Solve for x<br> 6x + 9 &lt; 63
ZanzabumX [31]

Answer:

x < 9

Step-by-step explanation:

Given inequality:

6x + 9 < 63

Subtract 9 from both sides:

⇒ 6x + 9 - 9 < 63 - 9

⇒ 6x < 54

Divide both sides by 6:

⇒ 6x ÷ 6 < 54 ÷ 6

⇒ x < 9

Three consecutive integers have a sum of 48 find the integers?
zavuch27 [327]

The sum of three consecutive integers is three times the middle one: if we call the middle one x, the three numbers are

x-1,\ x,\ x+1

So, their sum is x-1+x+x+1 = 3x

Which is three times the middle one.

So, if the sum of three consecutive intergers is 48, the middle one must be 48/3 = 16.

So, the three numbers are 15, 16 and 17

Rose is fishing from a small boat. A fish swimming at the same depth as the hook at the end of her fishing line is 8 meters away
tensa zangetsu [6.8K]

The question is incomplete, as the depth of the hook isn't given in the question. However, using a proposed depth for the hook, we could give a stepwise solution to the exercise.

Answer:

Kindly check explanation

Step-by-step explanation:

If given a hook depth of 6 meters, and a distance of 8 m(fishing line from hook) at the the Same depth, then the distance between rose and the fish, x can be calculated, using the relation.

Hypotenus² = opposite² + adjacent²

(refer to attached picture)

x² = 6² + 8²

x² = 36 +. 64

x² = 100

x = sqrt(100)

x = 10 meters

You can use the actual depth value to obtain the actual solution to your question.
