Answer:

See below.

Step-by-step explanation:

4.2 is 4 and 2 tenths.

4 is 40 tenths.

That means that 4.2 is 40 tenths plus 2 tenths, or 42 tenths.

First line: 4.2 / 6 = 42 tenths / 6

In the second line, we divide 42 tenths by 6. Since 42 divided by 6 = 7, then 42 tenths divided by 6 equals 7 tenths.

Second line: 4.2 / 6 = 7 tenths

In the third line, we write 7 tenths as a number. 7 tenths is the same as 0.7.

Third line: 4.2 / 6 = 0.7

Answer:

10

Step-by-step explanation:

10 is the greatest common factor that you can divide into both 40 and 50.

Answer:

10

Step-by-step explanation:

Try and find the prime factorization of 40 and 50.

40=2*2*2*5

50=2*5*5

Multiply the prime  factors that are common to both numbers.

2*5=10

Answer:

84

Step-by-step explanation:

m∠CMT=101-54=47

m∠PMA=37, So

m∠PMA+m∠CMT=47+37=84

The sum of the angle ∠PMA + ∠CMT will be 84 so option (D) will be correct.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

In other words, the angle is the measurement of the angular distance. For instance, we have a meter and an inch for linear motion, but we don't have a measurement for angular rotation, therefore the angle is helpful in determining angular rotation.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

The Angle of description has given below

∠CMT=101-54=47

∠PMA=37, means

∠PMA+∠CMT = 47+37 = 84 hence, 84 will be the correct answer.

Answer:

16. 3

17. 12 / 7

18. 24 / 5 ( or ) 4.8

Step-by-step explanation:

16.

2 / ( x - 1 ) = 1

2 = x - 1

x = 2 + 1

x = 3

17.

( x / 3 ) + ( x / 4 ) = 1

LCM ( 3, 4 ) = 12

x / 3 = 4x / 12

x / 4 = 3x / 12

( x / 3 ) + ( x / 4 ) = 1

( 4x / 12 ) + ( 3x + 12 ) = 1

( 4x + 3x ) / 12 = 1

7x / 12 = 1

7x = 12

x = 12 / 7

18.

( x / 3 ) + ( x / 2 ) = 4

LCM ( 3, 2 ) = 6

x / 3 = 2x / 6

x / 2 = 3x / 6

( x / 3 ) + ( x / 2 ) = 4

( 2x / 6 ) + ( 3x / 6 ) = 4

( 2x + 3x ) / 6 = 4

5x / 6 = 4

5x = 24

x = 24 / 5

x = 4.8

Step-by-step explanation:

Using simple mathematical operations we know that Sunita's truly hourly wage is $38.

The four mathematical operations are functions that change one number into another by taking input values, or numbers, as inputs.

They include addition, subtraction, multiplication, and division.

So, she works nine hours a day, after all.

She worked 162 hours total over the course of 18 days, or 18 x 9 hours.

Also, it is understood that she gets one paid day off for every 18 hours worked.

She is therefore paid for nine hours each day.

She is compensated for a total of 19 x 9 = 171 hours.

She receives hourly pay of $36,

Her total compensation is 171 divided by 36, or $6156.

Actual wages = Total amount she was paid/Total hours she worked

= 6156/612

= 38

Therefore, using simple mathematical operations we know that Sunita's truly hourly wage is $38.

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, equilateral, scalene, obtuse, acute and right angled triangle.

In a right angled triangle, the hypotenuse is the side with the longest length. Pythagoras theorem states that the square of the hypotenuse is equal to the sum of the square of the remaining two legs

The value of x can be gotten using Pythagoras theorem.

y² = h² + 3²   (1)

x² = h² + 3²   (2)

(3 + 3)² = x² + y² (3)

Substituting y² = h² + 3²  and x² = h² + 3² into equation 3 gives:

(3 + 3)² = (h² + 3²) + (h² + 3²)

36 = h² + h² + 9 + 9

2h² + 18 = 36

2h² = 18

h² = 9

h = 3

Put h = 3, into equation 2 to get the value of x:

x² = 3² + 3²

x² = 9 + 9 = 18

x = √18 = 3√2 units

Answer:

x = 4 and y = -6

Step-by-step explanation:

Solve by elimination by multiplying the first equation by -2:

-8x - 6y = 4

8x + 3y = 14

Add them together and solve for y:

-3y = 18

y = -6

Plug in -6 as y into one of the equations and solve for x:

8x + 3y = 14

8x + 3(-6) = 14

8x - 18 = 14

8x = 32

x = 4

So, the solution is x = 4 and y = -6

Answer:

x = 4​

y = -6

Step-by-step explanation:

4x + 3y = -2

8x + 3y = 14​

Multiply the second equation by -1

4x + 3y = -2

-8x - 3y = -14

--------------------------

-4x       = -16

Divide by -4

-4x/-4 = -16/-4

x = 4​

4x+3y = -2

4*4 +3y = -2

16 +3y = -2

3y = -2-16

3y = -18

y = -6

Answer:

[tex]x=1\frac{2}{9} +1\frac{1}{9}y[/tex]

Step-by-step explanation:

x - 3y + 8x - 7y = 5 + 6

9x - 10y = 11

9x - 10y + 10y = 11 + 10y

9x = 11 + 10y

9x ÷ 9 = 11 + 10y ÷ 9

[tex]x=1\frac{2}{9} +1\frac{1}{9}y[/tex]

Answer:

x = -1

y = -2

Step-by-step explanation:

x - 3y = 5     ----------------(I)

8x - 7y = 6 ----------(II)

Multiply equation (I) by (-8) and then add the two equations

(I)*(-8)     -8x + 24y = -40

(II)           8x   - 7y   = 6    {Now add and x will be eliminated}

                       17y = -34     {Divide both sides by 17}

                           y = -34/17

y = -2

Plugin  y  =-2 in equation (I)

x - 3*(-2) = 5

x  + 6 = 5         {Subtract 6 from both sides}

     x = 5 - 6

x = - 1
