Answer:
The number is 13 /24
Step-by-step explanation:
Let the number = x
x - (- 11/12) = 3x - 1/6
x + 11/12 = 3x - 1/6
Collect like terms ;
x - 3x = - 1/6 - 11/12
-2x = (-2 - 11) / 12
-2x = - 13 / 12
-2x(12) = - 13
-24x = - 13
x = 13 / 24
solve 5kx+6=7kx for x

Now,
Using the Parallel lines properties,
Angles [tex]1\ and\ 3[/tex] are vertical angles - True.The value of angle [tex]7\ is\ 125[/tex] degrees - False. Angles [tex]1\ and\ 6[/tex] are alternate interior angles - False.Angles [tex]3\ and\ 5[/tex] are alternate interior angles - True.Angles [tex]4\ and\ 8[/tex] are corresponding angles - True.The value of angle [tex]5\ is\ 55[/tex] degrees - True.Angles [tex]1\ and\ 7[/tex] are alternate exterior angles - True. Angles [tex]6\ and\ 8[/tex] are corresponding angles - False.Angles [tex]1\ and\ 6[/tex] are supplementary angles - False. Angles [tex]4\ and\ 8[/tex] are supplementary angles - False.Hence, we can say that As Parallel lines L and M are intersected by line N, so given questions have following answers True, False, False, True, True, True, True, False, False, False.

An equilateral triangle with side length 1 cm is shown in the diagram, work out the height of the triangle.
Give your answer rounded to 1 DP.
Answer:
0.9 cm
Step-by-step explanation:
c is the length of the side. a is the altitude. b is the base. a is the vertical bisector if the base, so the base is 0.5 cm.
c² = a² + b²
1² = a² + 0.5²
1² - 0.5² = a²
1 - 0.25 = a²
√0.75 = a
0.8660254 = a
round to 0.9
4x + 3(4x + 7) = 4(7x + 3)
Answer: 1
Step-by-step explanation:4x + 3(4x + 7) = 4(7x + 3) + -3
Reorder the terms:
4x + 3(7 + 4x) = 4(7x + 3) + -3
4x + (7 * 3 + 4x * 3) = 4(7x + 3) + -3
4x + (21 + 12x) = 4(7x + 3) + -3
Reorder the terms:
21 + 4x + 12x = 4(7x + 3) + -3
Combine like terms: 4x + 12x = 16x
21 + 16x = 4(7x + 3) + -3
Reorder the terms:
21 + 16x = 4(3 + 7x) + -3
21 + 16x = (3 * 4 + 7x * 4) + -3
21 + 16x = (12 + 28x) + -3
Reorder the terms:
21 + 16x = 12 + -3 + 28x
Combine like terms: 12 + -3 = 9
21 + 16x = 9 + 28x
Solving
21 + 16x = 9 + 28x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-28x' to each side of the equation.
21 + 16x + -28x = 9 + 28x + -28x
Combine like terms: 16x + -28x = -12x
21 + -12x = 9 + 28x + -28x
Combine like terms: 28x + -28x = 0
21 + -12x = 9 + 0
21 + -12x = 9
Add '-21' to each side of the equation.
21 + -21 + -12x = 9 + -21
Combine like terms: 21 + -21 = 0
0 + -12x = 9 + -21
-12x = 9 + -21
Combine like terms: 9 + -21 = -12
-12x = -12
Divide each side by -12.

?/h=h/?
Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

If triangle JKL is similar to triangle RST then the value of x is 15.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
Triangle JKL is similar to triangle RST
Let us find the value of x by forming a proportional equation
10/x = 8/12
Apply cross multiplication
120=8x
Divide both sides by 8
x=15
Hence, if triangle JKL is similar to triangle RST then the value of x is 15.

Three lions and three tigers are walking in a row to get ice cream. The lions are fighting so they are not walking next to each other. in how many different ways can the three lions and three tigers walk if no two lions are the same and no two tigers are the same?
Answer:
72
Step-by-step explanation:
As 3 lions & 3 tigers are to be arranged in a way that lions are not together. It can be done as per following arrangements
LTLTLT , or TLTLTL
Lions can be positioned in six ways, Tigers can also be positioned in 6 ways. There are two alternative positions.
Hence the arrangement can be done in 2 x 6 x 6 = 72 ways
The different ways should be 72.
calculation:As 3 lions & 3 tigers are to be arranged
