i

100-10-30-25=35

ii

150-20-25=105

Answer:

10x-5

Step-by-step explanation:

Just multiply 5 by 2 and you get 10x and then multiply 5 by 1 which is 5 and use the minus symbol in the expression

so 10x-5

Answer:

on 4x + 33 = 10x + 3, we could use inverse operation and move 10x to left side, which will create -6x+33=3. we could also use the same thing to 33 and get -6x=-30. if we divide -30 by -6, we would get 5

Step-by-step explanation:

4+33=10+3

4+33−33=10+3−33

4=10−3

=5

Answer:

(3,-12)

x = 3, y = -12

Step-by-step explanation:

(1) y=x-15

(2) y=-4x

solve equation (1) for x:

add 15 to both sides

x=y+15

plug in x=y+15 into equation (2):

y=-4(y+15)

y=-4y - 60

5y = -60

y = -12

plug in y=-12 into equation (2):

-12 = -4x

3 = x

Answer:

5

Step-by-step explanation:

Since both triangles are similar then see if two dimension match up, so 9 is like 45, therefore, they multiplied 9 x 5 to get 45, so the scale factor (number you multiply to get the new value) is 5, since it grew 5 times

Answer:

  x = 20°

Step-by-step explanation:

For questions like this, it is helpful to remember that an exterior angle is equal to the sum of the remote interior angles.

  110° = 2x + 70°

  40° = 2x

  20° = x

_____

Similarly, ...

  y = x + 70° = 20° +70°

  y = 90°

In math, the '!' sign are used in factorial. Factorial is multiplications on numbers itself and with another numbers that less than the number itself. Example :

5! =5x4x3x2x1 or nx(n-1)x(n-2)...2x1

Answer: 1: (2/v) 2: (3/m^4) 3: (4/x^4) 4: (1/k^3)

Step-by-step explanation:

When there is a negative exponent, the variable moves from the numerator (top) to the denominator (bottom), which gets rid of the negative sign in front of the exponent. MOVE ONLY THE VARIABLE AND CORRECT EXPONENT!!

Answer:

10

Step-by-step explanation:

by Pythagoras theorem,

PR^2=PQ^2+PR^2

Therefore,PR=√(PQ^2+PR^2)

=√(6^2+8^2)

=√100

=10

The table be like

Mike age        kellie age

10                     14

15                     19

20                    24

25                    29

Since Mike's sister, Kellie, is 4 years older than he is

And, Let m be Mike's age and let k be Kellie's age.

So here the equation be like

k = m + 4

Based on this we can compute the ages and fill the table

Step-by-step explanation:

Point A describes the context A) (2,16), If Amy works 2 hours,

she will earn $16.

An ordered pair is made up of the ordinate and the abscissa of the x coordinate, with two values given in parenthesis in a certain sequence.

Pair in Order = (x, y)

x is the abscissa, the distance measure of a point from the primary axis x

y is the ordinate, the distance measure of a point from the secondary axis y

Given, A point on a coordinate plane A(2, 16), The x-coordinate is the number of hours and the y-coordinate is the amount earned in dollars.

From this and the given options, we conclude that the correct option is

1.8 x 1 x 2 = 3.6

Answer:

27

Step-by-step explanation:

note that tanx cotx = tanx × [tex]\frac{1}{tanx}[/tex] = 1

Given

tanx - cotx = 5 ( square both sides )

(tanx - cotx)² = 5² = 25 ← expand left side using FOIL

tan²x - 2tanxcotx + cot²x = 25

tan²x - 2 + cot²x = 25 ( add 2 to both sides )

tan²x + cot²x = 27

Answer:

Step-by-step explanation:

just took the quiz

The equation representing the circle A is (x – 4)² + (y + 5)² = 36.

A circle is a spherical shape without boundaries or edges. A circle is a closed, curved object with two dimensions in geometry.

The general equation of circle is given by equation

( x - h )² + ( y - k )² = r²

Where,  ( h, k ) is the centre and 'r' is the radius.

As, the circle has a shift of 4 units on the +x axis.

The circle has a shift of the 5 units on the -y axis.

As, the circle has a radius of 6 units from the graph.

So, (h,k) = (4, -5).

Substitute the values of (h,k) in the general equation of the circle.

( x - 4 )² + ( y - (-5) )² = 6²

( x - 4 )² + ( y + 5 )² = 36

Therefore, the equation of circle becomes ( x - 4 )² + ( y + 5 )² = 36.

whats the question?

Step-by-step explanation:

Answer:

By closure property of multiplication and addition of integers,

If [tex]x + \dfrac{1}{x}[/tex] is an integer

∴ [tex]\left ( x + \dfrac{1}{x} \right) ^3 = x^3 + \dfrac{1}{x^3} +3\cdot \left (x + \dfrac{1}{x} \right )[/tex] is an integer

From which we have;

[tex]x^3 + \dfrac{1}{x^3}[/tex] is an integer

Step-by-step explanation:

The given expression for the positive integer is x + x⁻¹

The given expression can be written as follows;

[tex]x + \dfrac{1}{x}[/tex]

By finding the given expression raised to the power 3, sing Wolfram Alpha online, we we have;

[tex]\left ( x + \dfrac{1}{x} \right) ^3 = x^3 + \dfrac{1}{x^3} +3\cdot x + \dfrac{3}{x}[/tex]

By simplification of the cube of the given integer expressions, we have;

[tex]\left ( x + \dfrac{1}{x} \right) ^3 = x^3 + \dfrac{1}{x^3} +3\cdot \left (x + \dfrac{1}{x} \right )[/tex]

Therefore, we have;

[tex]\left ( x + \dfrac{1}{x} \right) ^3 - 3\cdot \left (x + \dfrac{1}{x} \right )= x^3 + \dfrac{1}{x^3}[/tex]

By rearranging, we get;

[tex]x^3 + \dfrac{1}{x^3} = \left ( x + \dfrac{1}{x} \right) ^3 - 3\cdot \left (x + \dfrac{1}{x} \right )[/tex]

Given that  [tex]x + \dfrac{1}{x}[/tex] is an integer, from the closure property, the product of two integers is always an integer, we have;

[tex]\left ( x + \dfrac{1}{x} \right) ^3[/tex] is an integer and [tex]3\cdot \left (x + \dfrac{1}{x} \right )[/tex] is also an integer

Similarly the sum of two integers is always an integer, we have;

[tex]\left ( x + \dfrac{1}{x} \right) ^3 + \left(- 3\cdot \left (x + \dfrac{1}{x} \right ) \right )[/tex] is an integer

[tex]\therefore x^3 + \dfrac{1}{x^3} = \left ( x + \dfrac{1}{x} \right) ^3 - 3\cdot \left (x + \dfrac{1}{x} \right )= \left ( x + \dfrac{1}{x} \right) ^3 + \left(- 3\cdot \left (x + \dfrac{1}{x} \right ) \right )[/tex] is an integer

From which we have;

[tex]x^3 + \dfrac{1}{x^3}[/tex] is an integer.

Step-by-step explanation:

1.

radius = 3 m

diameter = 3 × 2 = 6 m

formula = π × d

circumference = π × 6 = 18.85 m

2.

radius = 18 ÷ 2 = 9 cm

diameter = 18 cm
