There were 45 runners sister erased in the first half of the race 2/3 of them dropped out in the second half of the race to fifth of the remaining runners chopped out how many runners finish the race

Answer:

[tex](t,50-t) = \{(10,40),(20,30),(25,25)\}[/tex]

Step-by-step explanation:

Given

[tex]Expression: 50 - t[/tex]

Required

Evaluate when:

[tex]t = \{10,20,25\}[/tex]

When [tex]t =10.[/tex]

The expression is:

[tex]50 - t = 50 - 10[/tex]

[tex]50 - t = 40[/tex]

When t = 20

The expression is:

[tex]50 - t = 50 - 20[/tex]

[tex]50 - t =30[/tex]

When [tex]t = 25[/tex]

The expression is:

[tex]50 - t = 50 - 25[/tex]

[tex]50 - t =25[/tex]

The result is:

[tex](t,50-t) = \{(10,40),(20,30),(25,25)\}[/tex]

100 is the answer okay

Answer:  g = 5/7

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

Work Shown:

Let's move the -3/7 to the other side, to fully isolate g.

We do so by adding 3/7 to both sides (to undo the subtraction)

[tex]g - \frac{3}{7} = \frac{2}{7}\\\\g - \frac{3}{7}+\frac{3}{7} = \frac{2}{7}+\frac{3}{7}\\\\g = \frac{2+3}{7}\\\\g = \frac{5}{7}\\\\[/tex]

Luckily all of the denominators are the same (7), so we can add the fractions by adding the numerators to place that sum over the common denominator.

Step-by-step explanation:

(3)

The opposite sides of a parallelogram are congruent, so

6x = 3x + 15 ( subtract 3x from both sides )

3x = 15 ( divide both sides by 3 )

x = 5

and

2y - 10 = y + 5 ( subtract 5 from both sides )

y - 10 = 5 ( add 10 to both sides )

y = 15

Then x = 5 and y = 15

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

(4)

The diagonals of a parallelogram bisect each other, thus

y = 4x - 6 → (1)

9x - 25 = 2y → (2)

Substitute y = 4x - 6 into (2)

9x - 25 = 2(4x - 6)

9x - 25 = 8x - 12 ( subtract 8x from both sides )

x - 25 = - 12 ( add 25 to both sides )

x = 13

Substitute x = 13 into (1)

y = 4(13) - 6 = 52 - 6 = 46

Then x = 13 and y = 46

Answer:

y=-x+15

Step-by-step explanation:

hope this helps :)

Step-by-step explanation:

Supplementary angles add up to 180°. so,

2x+15 + 3x+5 = 180

5x+20=180

Subtract 20 from both sides

5x=160

Divide both sides by 5

x=32

Plug that into 2x+15, F = 64+15 = 79

for 3x+5, G = 96 +5 = 101

Answer:

25. a = 60

26. a = 17

Step-by-step explanation:

In these two problems we are going to use a property of parallelograms that says: opposite angles have equal measure

so we have

25.

[tex]6a+10=130\\\\6a=130-10\\\\6a=120\\\\a=60[/tex]

and for 26 we have

[tex]4a-4=2a+30\\\\4a=2a+30+4\\\\4a=2a+34\\\\4a-2a=34\\\\2a=34\\\\a=17[/tex]

Answer:

Both lines have a slope of 5, therefore they are parallel lines.

Step-by-step explanation:

The equation of line L₁, is y=5x+1 The equation of line L₂ is 2y-10x+3=0 Show that these two lines are parallel.

As we know, the Parallel lines have equal slopes

The slop intercept form is y = mx + c

Where m is the slope and c is the y-intercept.

Consider the line L₁,

y = 5x + 1 is in the slop intercept form where slope m = 5

Now consider the line L₂.

Write L₂, 2y-10x+3=0 into slope-intercept form

[tex]2y=10x-3[/tex]

[tex]y=5x-\frac{3}{2}[/tex]

The slope of the lines L₂ is m = 5.

Since both lines have a slope of 5, therefore they are parallel lines.

Answer:

60 minutes

Step-by-step explanation:

Step 1

We Find and list multiples of each number of minutes that each person walked around the deck until the first common multiple is found. This is the lowest common multiple.

Multiples of 4:

4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68

Multiples of 5:

5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70

Multiples of 6:

6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72

Therefore,

LCM(4, 5, 6) = 60

They would meet again at starting point after 60 minutes

Answer:

slope = -1

Step-by-step explanation:

Use the slope formula [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex] to find the slope. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and the [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. So, we'll use the points given in the question, (-2,6) and (9, -5). Substitute -2 for [tex]x_1[/tex], 6 for [tex]y_1[/tex], 9 for [tex]x_2[/tex], and -5 for [tex]y_2[/tex]. Then, solve:

[tex]\frac{(-5)-(6)}{(9)-(-2)} \\= \frac{-5-6}{9+2} \\= \frac{-11}{11} \\= -1\\[/tex]

Therefore, the slope is -1.

The slope of the line that passes through the points (-2, 6) and (9, -5) is -1.

A slope is also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

Given the coordinates of the two points on the graph is (-2, 6) and (9, -5). Therefore, the slope of the line that passes through this point is,
Slope = [6 - (-5)] / [-2 - 9]

Slope = (11) / (-11)

Slope = -1

Hence, the slope of the line will be -1.

Answer:

  not a right triangle

Step-by-step explanation:

The perimeter is 22, so we have ...

  AB +BC +CA = 22

  8 + 5 + CA = 22

  CA = 22 -13 = 9

If this is a right triangle, the sum of the squares of the short sides will be equal to the square of the long side.

  AB² +BC² = 8² +5² = 64 +25 = 89

This is not the same as ...

  CA² = 9² = 81

The triangle is not a right triangle.

Additional comment

If you're familiar with a few Pythagorean triples, you know that a couple involving a side length 5 are (3, 4, 5) and (5, 12, 13). That is, (5, 8, 9) is NOT a Pythagorean triple, so you know immediately that those side lengths do not form a right triangle. (No calculation is necessary.)

Normally here you would divide by 2, but you don’t need two because there is 2 triangles that are the same

Add the 50.41 and the 16.86 and you have your answer!
