35+ x + 60 = 180

95 + x = 180

x = 180 – 95

x = 85

x + 47 + 75 = 180

x + 122 = 180

x = 180 – 120

x = 58

105 ° = 3 x° –> Opposite angles ,

x = 105 / 3

x = 35

3x = 3(35) = 105°

Answer:

6 seconds

Step-by-step explanation:

h(x)=-(x-2)^2+16

We want h(x) to be 0 ( that is when the ball hits the ground)

0 = -(x-2)^2+16

Subtract 16 from each side

-16  = -(x-2)^2+16-16

-16 = -(x-2)^2

Divide by -1

16 = (x-2)^2

Take the square root of each side

sqrt(16) = sqrt((x-2)^2)

±4 = x-2

Add 2 to each side

2±4 = x-2+2

2±4 =x

2+4 = x   2-4 = x

6 =x  -2 =x

Time cannot be negative so x=6

Answer:

X = 6

Answer:

Step-by-step explanation:

x = first number

x + 2 = second number

x + 4 = third number

5(x + 2) = 6 + 2x + 2 ( x + 4)

5x + 10 = 6 + 2x + 2x +8

5x - 4x = 14 - 10

x = 4

The first number (x) = 4

The second number ( x + 2) = 4 + 2 = 6

The third number (x + 4) = 4 + 4 = 8

Answer:

2x + 2x +2 + 2x +4 = 6x +6 =Sum

5 * (2x +2) = 2 * (2x + 2x +4) +6

10x + 10 = 8x + 8 + 6

2x = 4

x = 2

So the numbers are:

2x or 4

2 x + 2 = 6

2x + 4 = 8

Double-Check

5 * 2nd integer = 30

2 *  (1st + 3rd integers) = 24

30 is 6 more than 24

Success!!!

Step-by-step explanation:

[tex]\\ \sf\longmapsto -2x-4>8[/tex]

[tex]\\ \sf\longmapsto -2(x+4)>8[/tex]

[tex]\\ \sf\longmapsto x+4>\dfrac{8}{-2}[/tex]

[tex]\\ \sf\longmapsto x+4>-4[/tex]

[tex]\\ \sf\longmapsto x>-4-4[/tex]

[tex]\\ \sf\longmapsto x>-8[/tex]

Answer:

x < -6

Step-by-step explanation:

-2x - 4 > 8

Add 4 on both sides

-2x > 12

Divide -2 on both sides

x < -6

Hope this helps!

Answer:

[tex] \frac{271}{100} [/tex]

Step-by-step explanation:

hopefully it makes sense

:)

The decimal 2.71 can be written as the simplified fraction as 271/100.

Fractions are type of numbers which are written in the form p/q, which implies that p parts in a whole of q.

Here p, called the numerator and q, called the denominator, are real numbers.

The given number is 2.71.

We can write 2.71 as 2.71 / 1, since any number divided by 1 is the number itself.

Multiplying both numerator and denominator of 2.71 / 1 with 100, we get,

(2.71 × 100) / (1 × 100)

= 271/100

This cannot be simplified further since 271 is a prime number.

Hence the simplified fractional form of 2.71 is 271/100.

Step-by-step explanation:

Add all the data and divide by 2 to get your median

The median of the data set 8, 8, 14, 15, 15, 15.4, 17, 23, 38.5 will be 15.

The median of the data is the middle value of the data which is also known as the central tendency of the data and is known as the median.

The data set is given below.

17, 8, 23, 14, 15, 38.5, 8, 15.4

Arrange the data in ascending order, then we have

8, 8, 14, 15, 15, 15.4, 17, 23, 38.5

The number of the term will be 9, then the median will be

Median = (n + 1) / 2

Median = (9 + 1) / 2

Median = 10 / 2

Median = 5th term

5th term that is 15.

The median of the data set 8, 8, 14, 15, 15, 15.4, 17, 23, 38.5 will be 15.

Answer:

A = (Y + 5)/ D

Step-by-step explanation:

Y = AD - 5

Y + 5 = AD - 5 + 5

Y + 5 = AD

(Y + 5)/D = AD/D

(Y + 5)/ D = A

》A = (Y + 5)/ D

Answer:

q is 4

Step-by-step explanation:

[tex]gradient = \frac{y_{2} - y_{1} }{x _{2} - x _{1} } \\ [/tex]

let gradient of the line joining (4, q) to (6, 5) be x

let gradient of the line joining (0, 0) to (4, q) be y

[tex]y = 2x[/tex]

therefore:

[tex]( \frac{q - 0}{4 - 0} ) = 2( \frac{5 - q}{6 - 4} ) \\ \\ \frac{q}{4} = \frac{2(5 - q)}{2} \\ \\ \frac{q}{4} = 5 - q \\ \\ q = 4(5 - q) \\ q = 20 - 4q[/tex]

collect like terms:

[tex]q + 4q = 20 \\ 5q = 20 \\ q = \frac{20}{5} \\ \\ q = 4[/tex]

Let,

As we know,

then,

→ [tex]\frac{q-0}{4-0} = 2(\frac{5-q}{6-4} )[/tex]

      [tex]\frac{q}{4} = \frac{2(5-q)}{2}[/tex]

      [tex]\frac{q}{4} = 5-q[/tex]

By applying cross-multiplication, we get

      [tex]q = 4(5-q)[/tex]

      [tex]q = 20-4q[/tex]

By adding "4q" both sides, we get

[tex]q+4q= 20-4q+4q[/tex]

     [tex]5q = 20[/tex]

       [tex]q = \frac{20}{5}[/tex]

       [tex]q = 4[/tex]

Thus the above value is correct.

Step-by-step explanation:

Hi

The value of the expression is a decimal -17.33.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

0.3x = -5 - (-0.4 - (-0.6))

0.3x = -5 - (-0.4 + 0.6)

0.3x = -5 - 0.2

0.3x = -5.2

x = -5.2/0.3

x = -17.33

Thus,

The value of x is -17.33.

e^0=x^2-25=1

x^2=26

x=sqrt(26), pos and neg

The potential solution of the given equation is x=±√26. Therefore, option C is the correct answer.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

The given equation is ln(x²-25)=0

x²-25>0

(x+5)(x-5)>0 (∵a²-b²=(a+b)(a-b))

x>-5 and x>5

Now, e⁰=x²-25

1=x²-25

x²=26

x=±√26

Therefore, option C is the correct answer.

120°

Step-by-step explanation:

Answer:

-5

Step-by-step explanation:

(-5)(-5)(-5)=-125

Given the expression:

[tex] \displaystyle \large{ \sqrt[3]{ - 125} }[/tex]

Definition:

[tex] \displaystyle \large{ y = \begin{cases} \pm \sqrt[n]{x} \longrightarrow n = (2,4,6,8,...) \: \: (x \geqslant 0) \\ \sqrt[n]{x}\longrightarrow n = (1,3,5,7,...) \: \: (x \in \R) \end{cases}}[/tex]

First, factor the -125. -125 comes from (-5)×(-5)×(-5) or (-5)^3.

[tex] \displaystyle \large{ \sqrt[3]{ ( - 5) \times ( - 5) \times ( - 5)} }[/tex]

Because if (-5)^2 = 25 then 25×(-5) again will be -125.

Since this is the cube root, we have to pull out 3 terms in one. There are 3 fives that we can take off and therefore,

[tex] \displaystyle \large \boxed{ - 5}[/tex]

Fractions can be evaluated, same way non fractions are evaluated

The result of the fraction expression [tex]\mathbf{\dfrac {9}m+4}[/tex] is 7

The given parameters are:

[tex]\mathbf{\dfrac {9}m+4}[/tex]

[tex]\mathbf{m = 3}[/tex]

So, we have:

[tex]\mathbf{\dfrac {9}m+4}[/tex]

Substitute 3 for m

[tex]\mathbf{\dfrac {9}m+4 = \dfrac {9}3+4}[/tex]

Evaluate the division

[tex]\mathbf{\dfrac {9}m+4 = 3+4}[/tex]

Add 3 and 4

[tex]\mathbf{\dfrac {9}m+4 = 7}[/tex]
