Im struggling with this one please help, thank you!

Answer:

x=7

Step-by-step explanation:

Since this is an isosceles triangle the two angles are equal.

3x+6 = 5x-8

Subtract 3x from each side

3x+6-3x = 5x-8-3x

6 = 2x-8

Add 8 to each side

6+8 = 2x-8+8

14 = 2x

Divide each side by 2

14/2 = 2x/2

7 = x

Answer:

x = 7

Step-by-step explanation:

Its two angle is equal so, it is isosceles triangle.

3 x + 6 = 5 x - 8 .. ( in isosceles triangle two side are equal).

3 x + 6 = 5 x - 8

Subtract 3 x from both side

3 x - 3 x + 6 = 5 x - 3 x - 8

6 = 2 x - 8

add 8 to each side

6 + 8 = 2 x - 8 + 8

14 = 2 x

Divide each side by 2

14 / 2 = 2 x / 2

7 = x

Answer:

Complementary angles

Step-by-step explanation:

Complementary angles are angles that add up to 90 degrees.

Answer:

complementary

Step-by-step explanation:

The angles are part of a right angle as shown by the square.

Complementary angles are angles that add up to 90˚

since x-15 and 2x are parts of the right angle, they add up to 90

Answer:

Whats the question?

Step-by-step explanation:

Answer:

Step-by-step explanation:

18/6=51/p

do cross multiplication

6*51=p*18

306/18=p

17=p

therefore perimeter is 17 cm

In a straight line, like the one presented before you, there is 180 degrees. So that means 115 degrees + x is gonna equal 180.

So that means, x is gonna be 180 - 115. So x is 65 degrees

Answer:

The mean gives Turner’s game average.

Step-by-step explanation:

The median describes the number in the middle from lowest to greatest. The mode describes the number that appears the most. The mean describes the average of the data set.

Answer:

In mathematics, the domain or set of departure of a function is the set into which all of the input of the function is constrained to fall. It is the set X in the notation f: X → Y, and is alternatively denoted as {\displaystyle \operatorname {dom} }.

Step-by-step explanation:

Formula

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

Absolute value

As the domain of absolute value refers to the set of all possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range of absolute value is the set of possible output values, which are shown on the y-axis.

Notation

We can write the domain of f(x) in set builder notation as, {x | x ≥ 0}. If the domain of a function is all real numbers (i.e. there are no restrictions on x), you can simply state the domain as, 'all real numbers,' or use the symbol to represent all real numbers.

Rules

If a function contains a square root, set the equation inside the square root greater or equal to zero and solve. The resulting answer is the domain. If a function contains a fraction, set the denominator not equal to zero and solve. The resulting answer is the domain.

hay claudia do u remember me

Given:

Lines DE and AB intersect at point C.

[tex]m\angle ACE=(2x+2)^\circ[/tex]

[tex]m\angle ECB=(5x+3)^\circ[/tex]

To find:

The value of x.

Solution:

In the given figure it is clear that the angles [tex]\angle ACE[/tex] and [tex]\angle ECB[/tex] are lie on a straight line AB.

[tex]m\angle ACE+m\angle ECB=[/tex]               [Linear pair]

[tex](2x+2)^\circ+(5x+3)^\circ=180^\circ[/tex]

[tex](7x+5)^\circ=180^\circ[/tex]

[tex]7x+5=180[/tex]

Subtract 5 from both sides.

[tex]7x=180-5[/tex]

[tex]7x=175[/tex]

Divide both sides by 7.

[tex]x=\dfrac{175}{7}[/tex]

[tex]x=25[/tex]

Therefore, the correct option is B.

Answer:

x = 25

Answer:

x = 2.5

Step-by-step explanation:

3.25x = 8.125

Divide each side by 3.25

3.25x/3.25 = 8.125/3.25

x =2.5

Answer:

x = 2.5

Step-by-step explanation:

3.25x = 8.125

then divide both sides by 3.25 to get x on its own

x = 2.5

The length of CD represents the distance between the points C and D. Counting the points between them, if we start from point D, we need to get through points 1, 2, and 3 to get to C. That is 3 units, or A

Answer:

190 feet below sea level

Step-by-step explanation:

d = -310 + 15m

d = -310 + 15(8)

d = -310 + 120

d = -190

Answer:

-2/5

Step-by-step explanation:

Given the expression

-4/5 ÷ 2

= -4/5 * 1/2

= (-4*1)/(5*2)

= -4/10

= -2/2 * 2/5

-2/5

Hence the required values is -2/5

Answer:

x = 46.7°

Step-by-step explanation:

We are given:

1.) Angle x

2.) Side opposite to angle x

3.) Hypotenuse

We have to find angle x, therefore Sin ratio would be used;

Sin(x) = Opposite / hypotenuse

Sin(x) = 4 / 5.5

x = Sin⁻¹(4/5.5)

x = 46.7°

Hope this helps!
