Answer:

——— < 0
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
———————————————— = ———
10 10
203
——— < 0

What is simplest form? Explain to me.
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: 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
The diagram shows a circle inside a rectangle....
Answer:
let [tex]x[/tex] = height of rectangle
Given:
height of rectangle = diameter of circlelength of rectangle = 3 × height of rectangleTherefore,
height of rectangle = [tex]x[/tex]diameter of circle = [tex]x[/tex]radius of circle = [tex]\dfrac{1}{2}x[/tex]length of rectangle = [tex]3x[/tex]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]

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
