If P is the midpoint of ST, SP=x+12 and PT=4x, determine the length of ST

Answers

Answer 1

Answer:

5x - 12

Step-by-step explanation:

If P is the midpoint of Line ST, then Lines SP and PT equal ST.

[tex]SP=x+12\\PT=4x\\SP+PT=x-12+4x\\SP+PT=5x-12\\ST=5x-12[/tex]

Answer 2

Answer:

ST = 32

Step-by-step explanation:

Since P  is the midpoint of ST , then

SP = PT , that is

x + 12 = 4x ( subtract x from both sides )

12 = 3x ( divide both sides by 3 )

4 = x

Then

ST = SP + PT = x + 12 + 4x = 5x + 12 , so

ST = 5(4) + 12 = 20 + 12 = 32

What are the coordinates of the point on the directed line segment from (−1,9) to (3,−7) that partitions the segment into a ratio of 5 to 3?

Answers

Answer:

[tex]$X=1.5, Y=0.75$[/tex]

Step-by-step explanation:

 Let the ends of the line segment be A(-1,9) and B(3,-7)

 Divided in the ratio m:n by a point P

 By formula of coordinate geometry,

[tex]$X=\frac{5 * 3+3 *(-1)}{5+3}$[/tex]

[tex]$Y=\frac{5 *(-7)+3 * 9}{5+3}$[/tex]

Help me with 24 “ find the value of x”

Answers

Answer:

x = 5°

Step-by-step explanation:

2x+20 = 3x +15 —> Opposite angles

3x - 2x = 20 - 15

x = 5

I hope I helped you^_^

Vertical angles are always congruent. Therefore you must set them equal to each other. If we set 2x+20=3x+15 we can do the math like so

2x+20=3x+15
-15 | -15
2x+5 | 3x
-2x | -2x
5 | X

Now to check the answer 2*5+20=30
3*5+20=30
30=30


X=5 is the correct answer. Hope this helped and happy geometry!

Teachers divided students into groups of 3. Each group of 3 wrote a report that had 9 pictures in it. The students used 585 pictures altogether. How many students were there in all?

Answers

Each group used 9 pictures, first divide total pictures by pictures per group to find total groups:

585 / 9 = 65 total groups.

Each group had 3 students.

Multiply total groups by students per group:

65 x 3 = 195 total students

Answer: 195 students.

They currently give me 15 euros a week, but I have convinced my parents to raise it for me by 12%. What will be my weekly money from now on.

Answers

Answer:

16.80 euros.

Step-by-step explanation:

12% = 0.12

So it will now be 15 + 15 * 0.12

= 16.80.

Answer:  16.80 euros

===========================================================

Explanation:

There are two approaches

The slightly slower approach is to do this

12% of 15 = 0.12*15 = 1.80

So you get an 1.80 euro raise and the new amount you get is 15+1.8 = 16.80 euros

The shortcut is to do this

1.12*15 = 16.80

This works because increasing by 12% is the same as taking 112% of that original amount.

The midpoint M of FG has coordinates (7, 19). Point Fhas coordinates (14, 18). Find the
coordinates of point G.

Answers

9514 1404 393

Answer:

  G(0, 20)

Step-by-step explanation:

G = 2M -F

G = 2(7, 19) -(14, 18) = (14 -14, 38 -18)

G = (0, 20)

__

Additional comment

This formula for finding the end point from the midpoint and the other end can be derived from the fact that the midpoint is the average of the endpoints.

  M = (F+G)/2

  2M = F+G . . . . . multiply by 2

  G = 2M -F . . . . . subtract F

Answer:

x=33

Step-by-step explanation:

The angles are same side interior angles and they add to 180 degrees

x+20 + 4x-5 = 180

Combine like terms

5x + 15 = 180

Subtract 15 from each side

5x +15-15 = 180-15

5x = 165

Divide by 5

5x/5 = 165/5

x=33

Now we have to,

→ find the required value of x.

The final output will be,

→ 180°

The equation we use to find the value,

→ (x+20) + (4x-5) = 180°

Let's find the required value of x,

→ (x+20) + (4x-5) = 180°

→ 5x +15 = 180°

→ 5x = 180 - 15

→ x = 165/5

→ [x = 33°]

The value of 4x will be,

→ 4x = 4 × 33

→ 132°

Let's check whether the required value of x is correct or incorrect,

→ (x+20) + (4x-5) = 180°

→ (33+20) + (132-5) = 180°

→ 53 + 127 = 180°

→ 180° = 180°

→ LHS = RHS

Hence, 33° is the required value of x.

Which inequality is represented by the graph

Answers

Answer:

y ≥ -2x + 2.5

Step-by-step explanation:

It's kind of hard to tell because no points are given on the graph, but we can first find the b value of 2.5 in the equation y = mx +b  as it is the y-intercept.

Using that value, we can also recognize that at one, it looks like the y-value is .5. using our slope formula (change in y / change in x), we can plug in the two points of (0, 2.5) and (1, 0.5) to get a slope of -2.

Now that we have our equation, we can make it an inequality!  

Since the graph is shaded upwards, we know it is going to be a greater than symbol, and since the line itself solid and not dotted, we know that the points on the line are also solutions, meaning that it is also equal to the line

Hence, we get the ≥ sign.

Putting it all together, we get our final equation of y ≥ -2x + 2.5 ! :))
