Equilateral triangles are triangles whose all sides and angles are equal.

Since the above given triangle has 3 equal sides it is an equilateral triangle.

So, the three angles of this triangle can be 3x.

Which means :

[tex] =\tt 3x = 180[/tex]

[tex] =\tt x = \frac{180}{3} [/tex]

[tex]\hookrightarrow \tt \color{plum}x = 60°[/tex]

▪︎Therefore, x = 60°

Answer:

x = 6

Step-by-step explanation:

Given that x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 25 when y = 100 , then

100 = 25k ( divide both sides by 25 )

4 = k

y = 4x ← equation of variation

When y = 24 , then

24 = 4x ( divide both sides by 4 )

6 = x

Answer:

There is a vertical asymptote at x = 4 because lim g(x) = ∝ and lim g(x) = -∝

Answer:

Step-by-step explanation:

Answer:

2^-2= 4^-1 =1\4

1\4=4

so I hope you get to it

Answer:

56

Step-by-step explanation:

Because there are 8 names  and when you choose a name there are 7 people that can be a pair so 7*8=56

Answer:

Step-by-step explanation:

Find the diagram attached

Using the similarity theorem

A F/F B = AG/GC

x+1/x+6 = x-1/x+3

Cross multiply

(x-1)(x+6) = (x+1)(x+3)

Expand

x²+6x-x-6 = x²+x+3x+3

5x - 6 = 4x+3

5x-4x = 3+6

x = 9

Hence the value of x is 9

Answer:

9

Step-by-step explanation:

3x+80=12x-1

80=12x-3x-1

80=9x-1

9x=80+1

9x=81

x=81/9

x=9

Answer:Let x be the number of full cup sold Let y be the number of half cup sold Whether the cup was full or not, they used 37 cups. Therefore, x + y = 37 How much money did they make selling half cup lemonade? They made y × 0.25 How much money did they make selling full cup lemonade? They made x × 0.50 Money made selling full cup + money made selling half cup = 15 x × 0.50 + y × 0.25 = 17 You end up with a system of linear equation to solved x + y = 37 x × 0.50 + y × 0.25 = 17 x + y = 37 equation 1 0.50x + 0.25y = 17 equation 2 Solve for y in equation 1 x + y = 37 x - x + y = 37 - x y = 37 - x Replace y in equation 2 0.50x + 0.25 (37 - x) = 17 0.50x + 0.25 × 37 - 0.25x = 17 0.50x + 9.25 - 0.25x = 17 0.25x + 9.25 = 17 0.25x + 9.25 - 9.25 = 17 - 9.25 0.25x = 17 - 9.25 0.25x = 7.75 Divide both sides by 0.25 0.25x/0.25 = 7.75/0.25 x = 31 y = 37 - x = 37 - 31 = 6 Sasha and Francisco sold 31 full cup and 6 half cup of lemonade It seems like people love their lemonade

Actually Welcome to the Concept of the Factorisation.

Since here both are the roots of the quadratic equation in the factor form, hence

equate them to zero, to get the value of x

hence,

2x-9 = 0

===> x = 9/2

and

3x+5=0

===> x = -5/3

Answer:

-46/45

Step-by-step explanation:

-2/9 + (-4/5)

can be re-written as

-2/9 - 4/5

which equals -46/45

if they want you to answer in decimal form, it will be -1.02

Answer:

−2x−28

Step-by-step explanation:

Distribute:

=(−4)(x)+(−4)(6)+(2)(x)+(2)(−2)

=−4x+−24+2x+−4

Combine Like Terms:

=−4x+−24+2x+−4

=(−4x+2x)+(−24+−4)

= −2x - 28

Answer:

12x+16

~Grouping~

12+16

4(3+4)

~Solution~

4(3+4)

Step-by-step explanation:

Hope that helps!!! :)

Answer:

Step-by-step explanation:

All you can do with this is take out a common factor of 4

12x / 4 = 3x

16  / 4 = 4

So the answer is

4 (3x + 4)

Answer:

  not a solution

Step-by-step explanation:

The given pair does not satisfy the second equation.

  y = -x + 5

  6 = -3 + 5 . . . . . . . . false for (x, y) = (3, 6)

The ordered pair is not a solution to the system of equations.

Answer:

sum of all angles =180

15° + 25° +(39+x) =180°

40° + 39 +x = 180

79° +x =180

x = 180 - 79

x. = 101

complete angel = 39 +x

= 39 + 101

= 140

There are no solutions. This question is impossible.

Step-by-step explanation:

Answer: 42 feet

Step-by-step explanation:

Let the length be x

Therefore, width = 2/3x

Area = Length × Width

Therefore, x × 2/3x = 1176

2/3x² = 1176

Divide both side by 2/3

x² = 1176 ÷ 2/3

x² = 1176 × 3/2

x² = 1764

x = ✓1764

x = 42

The length is 42 feet

Answer:

[tex]\frac{1}{4} = 2^{-2}[/tex]

[tex]\frac{1}{100} = 10^{-2}[/tex]

Step-by-step explanation:

The question is poorly formatted. However, I am able to get:

1. 1/4 and 2. 1/100

Required

Write as an expression of negative expression

1. 1/4.

Express 4 as 2^2

[tex]\frac{1}{4} = \frac{1}{2^2}[/tex]

Apply

law of indices [tex](\frac{1}{a^b} = a^{-b})[/tex]

[tex]\frac{1}{4} = 2^{-2}[/tex]

2. 1/100.

Express 100 as 4^2

[tex]\frac{1}{100} = \frac{1}{10^2}[/tex]

Apply law of indices [tex](\frac{1}{a^b} = a^{-b})[/tex]

[tex]\frac{1}{100} = 10^{-2}[/tex]
