8) If 15 balls cost Rs 225 then the cost of 8 balls is
Answer:
The cost of 8 balls is Rs $ 120.
Step-by-step explanation:
Given that 15 balls cost Rs $ 225, to determine the cost of 8 balls it is necessary to perform the following mathematical calculation:
(225/15) x 8 = X
15 x 8 = X
120 = X
Thus, the cost of 8 balls is Rs $ 120.

How can you find the sum of the angle measures in a triangle?
Answer:
a Euclidean space, the sum of angles of a triangle equals the straight angle (180 degrees, π radians, two right angles, or a half-turn). A triangle has three angles, one at each vertex, bounded by a pair of adjacent sides.

3(5x - 6) = 6(2x - 12)
Answer:
x = -18
Step-by-step explanation:
Distribute: 3*5x = 15x ; 3*-6 = -18 ; 6*2x = 12x ; 6*-12 = -72
15x - 18 = 12x - 72
Add 18 to both sides: 15x = 12x - 54
Subtract 12x from both sides: 3x = -54
Divide both sides by 3: x = -18
Answer:
x= 17.666666...
Step-by-step explanation:
3(5x - 6) = 6(2x - 12)
(3 times 5x , 3 times -6) (6 times 2x, 6 times - 12)
15x-18 = 12x -72 (multiply insides)
-12x -12x (remove 12x from right side)
3x-19 = -72 (product)
+19 = +19 (add 19 left side to remove it)
3x = 53 (product)
x = [tex]\frac{53}{3}[/tex] (divide)
x= 17.666666... (answer)
x = 17.67 (if simplify)

the length of a rectangle is 4 units more than it's width.The area of a rectangle is 25 more than 4 times the width.What is the width of the rectangle
Answer:
solution,
let width of the rectangle be x then,
length(l)=4x
Area(A)=25l
now,
area of rectangle = 4x×x
25×(4x)= 4x square 100x= 4xsquarex=25 unitsStep-by-step explanation:
in 2nd step one x cancel another in opposite side of =

Consider that polynomials are a family. Members of the family are monomials, binomials, and trinomials explain
Answer:
Monomials mean one
binomials mean two
trinomials mean three
Step-by-step explanation:
mono means one
bino means two
Trump means three
Answer:
monomial, binomial, and trinomial is a polynomial. They are special members of the family of polynomials and so they have special names. We use the words ‘monomial’, ‘binomial’, and ‘trinomial’ when referring to these special polynomials and just call all the rest ‘polynomials’.
polynomial—A monomial, or two or more monomials, combined by addition or subtraction
monomial—A polynomial with exactly one term
binomial— A polynomial with exactly two terms
trinomial—A polynomial with exactly three terms

N is between Mand Q MN-6X 4, and NO = 4x+2. If MO=20, what is MN?
4
8
2
20
Answer:
[tex]MN = 9.2[/tex]
Step-by-step explanation:
Given
[tex]MN = 6x - 4[/tex]
[tex]NO = 4x + 2[/tex]
[tex]MO = 20[/tex]
Required
Find MN
Since N is between M and O, then:
[tex]MO = MN + NO[/tex]
This gives:
[tex]20 = 6x - 4 + 4x + 2[/tex]
[tex]20 = 6x + 4x- 4 + 2[/tex]
[tex]20 = 10x -2[/tex]
[tex]10x = 20 +2[/tex]
[tex]10x = 22[/tex]
[tex]x = 2.2[/tex]
To solve for MN, substitute 1.4 for x in [tex]MN = 6x + 4[/tex]
[tex]MN = 6 * 2.2 - 4[/tex]
[tex]MN = 9.2[/tex]

I REALLY Need help ASAP
Answer:
A
Step-by-step explanation:
In order to multiply a whole number by a fraction, you can write the whole number in fraction form. -12 can also be written as [tex]\frac{-12}{1}[/tex].
Now you can write out [tex]\frac{-12}{1}[/tex] × [tex]\frac{20}{21}[/tex]
Multiply the numerators by each other and the denominators by each other to create one fraction.
-12 × 20 = -240 and 1 × 21 = 21
[tex]\frac{-12}{1}[/tex] × [tex]\frac{20}{12}[/tex] = [tex]\frac{-240}{21}[/tex] and now you can simplify the fraction by finding the greatest common factor of the denominator and numerator. -240 and 21 have the greatest common factor of 3. Divide each side by 3 and get the fraction -80/7
