Identifying the Error
Aaron claims the same answer could also be found by adding either –5 + 3 or –3 + 5.

What is the error in Aaron’s reasoning?
The commutative property is not true for addition.
The negative signs were switched.
The numbers are not in the correct order.
The associative property was used.

Answer:

Step-by-step explanation:

Common difference = 2nd term - 1st term = 11 - 5 = 6

a = 5

nth term = a + (n-1)d

               = 5 +( n-1) * 6

              = 5 + 6n - 6

             = 5 - 6 + 6n

              = 6n - 1

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.

Answer:

y = 6x

Step-by-step explanation:

if its $6 per person, each new person is gonna chagre $6

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: 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:

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

              1                     10
