The number of 5ths that equals 9 is gotten bus using multiplication property of equality by multiplying 9 by 5 to give; 45

We want to find the number of 5ths that equals 9. We can express this as;

¹/₅x = 9

Where x is the number that is multiplied with one - fifth to equal 9.

To solve it, we will apply multiplication property of equality by multiplying both sides by 5 to get;

x = 45

Thus, the number of 5ths that equals 9 is 45.

so x^2-10=0

we add 10 to both sides of the equation  x^2 = 10

then take the square root of both sides of the equation to eliminate the exponent on the left side  x = ± √10

The complete solution is the result of both the positive and negative portions of the solution. x = √10 ,−√10

the result can be shown in multiple forms

Answer:

x=10

Step-by-step explanation:

2(x − 3) = 14

2x+2 . -3 = 14

2x-16=14

2x-6+6=14+6

2x=14+6

2x=20

divide both sides by 2

Answer:

let [tex]x[/tex] = height of rectangle

Given:

Therefore,

Shaded area = area of rectangle - area of circle

Area of rectangle = length × height

                             = [tex]3x \times x[/tex]

                             = [tex]3x^2[/tex]

Area of circle = [tex]\pi r^2[/tex]

                       [tex]=\pi \left(\dfrac{1}{2}x\right)^2[/tex]

                       [tex]=\dfrac14\pi x^2[/tex]

[tex]\implies \textsf{shaded area}=3x^2-\dfrac14\pi x^2[/tex]

If the radius = 2 cm, then the diameter ([tex]x[/tex]) = 4 cm

Substituting [tex]x = 4[/tex] into the equation:

[tex]\implies \textsf{shaded area}=3(4)^2-\dfrac14\pi (4)^2[/tex]

[tex]\implies \textsf{shaded area}=48-4\pi[/tex]

[tex]\implies \textsf{shaded area}=4(12-\pi) \textsf{ cm}^2[/tex]

    10  

Step-by-step explanation:

Changes made to your input should not affect the solution:  

(1): "3.3" was replaced by "(33/10)".

Rearrange the equation by subtracting what is to the right of the greater than a sign from both sides of the inequality :

               3*(-1-2)-(-26-(33/10))<0

                  33

Simplify   ——

                  10

                   33

 -9 -  (-26 -  ——)  < 0  

                    10

Subtracting a fraction from a whole

Rewrite the whole as a fraction using  10  as the denominator :

           -26     -26 • 10

    -26 =  ———  =  ————————

            1         10    

Equivalent fraction: The fraction thus generated looks different but has the same value as the whole

the Common denominator: The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

         -26 • 10 - (33)                        -293

———————————————  =  ————

               10                                        10

           -293

 -9 -  ————  < 0  

              10

Subtracting a fraction from a whole

Rewrite the whole as a fraction using  10  as the denominator :

             -9              -9 • 10

    -9 =  ——  =  ———————

              1                     10  

Adding up the two equivalent fractions

        -9 • 10 - (-293)                           203

Answer: quotient is 20 up top number is

141 (R 20)

Step-by-step explanation:

Drop the three and you have 133.

What times 32 is 133

32 times four is 128

Now do 133 - 128 = 5

Drop the 2

What times 32 is 52

Well times two is 64 so it has to be times1

Now you have 52 - 32 to get your quotient of 20

Answer: The simplest form of a fraction is when the numerator and denominator of the fraction are relatively prime, which means that the numerator and denominator have no common factor.

Answer:

No.

The proportion breaks near the end because the multipliers no longer match.

Answer:

It is not proportional
