2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 9 as the denominator :
10 10 • 9
10 = —— = ——————

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 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:

When a fraction equals zero :
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
x-60
———— • 5 = 0 • 5
5
Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
x-60 = 0
Solving a Single Variable Equation:
4.2 Solve : x-60 = 0
Add 60 to both sides of the equation :
x = 60

The length of a rectangle is 5cm more then the width. the perimeter of the rectangle is 38cm.find the length and width of the rectangle?
Answer:
Length - 12
Width - 7
Step-by-step explanation:
38 = 2((5+x) + x)
38 = 10 +4x
28=4x
x=7
7+5=12
Given : The length of a rectangle is 5cm more then the width. The perimeter of the rectangle is 38cm. Find the length and width of the rectangle?
Solution : According to the question, here we are given that the length if the rectangle is 5m more than its breadth and so the perimeter of the rectangle is 38cm. So, for this let's check the steps below
Let's assume the breadth be B
So, as we got that length is 5cm more than Breadth which is B + 5cm
Perimeter is 38cm
★ Perimeter = 2(Length + Breadth) ★
Perimeter = 2(B + 5cm + B) 38cm = 2(2B + 5cm) 38cm/2 = 2B + 5cm 19cm - 5cm = 2B 2B = 14cm B = 7cmFinding Length
Length = B + 5cm = 7cm + 5cm = 12cm
Finding Breadth
Breadth(Width) = B = 7cm
Therefore, Width is 7cm whereas Length is 12cm

HELP ASAP ...........
Answer:
A
Step-by-step explanation:
Given
y - 2x - 8 = 0 ( add 2x + 8 to both sides )
y = 2x + 8 → (1)
y² + 8x = 0 → (2)
Substitute y = 2x + 8 into (2)
(2x + 8)² + 8x = 0 ← expand left side using FOIL and simplify
4x² + 32x + 64 + 8x = 0
4x² + 40x + 64 = 0 ( divide through by 4 )
x² + 10x + 16 = 0 ← in standard form
(x + 8)(x + 2) = 0 ← in factored form
x + 8 = 0 ⇒ x = - 8
x + 2 = 0 ⇒ x = - 2
Substitute these values into (1) for corresponding values of y
x = - 8 : y = 2(- 8) + 8 = - 16 + 8 = - 8 ⇒ P (- 8, - 8)
x = - 2 : y = 2(- 2) + 8 = - 4 + 8 = 4 ⇒ Q (- 2, 4 )
Calculate the length of PQ using the distance formula
PQ = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

PQ = [tex]\sqrt{(-2-(-8))^2+(4-(-8))^2}[/tex]
= [tex]\sqrt{(-2+8)^2+(4+8)^2}[/tex]
= [tex]\sqrt{6^2+12^2}[/tex]
= [tex]\sqrt{36+144}[/tex]
= [tex]\sqrt{180}[/tex]

is parallelogram a kite?
Answer:
Kites are a special type of quadrilateral with two distinct pairs of consecutive sides the same length. ... Similarly, every kite is not a parallelogram, because the opposite sides of a kite are not necessarily parallel.
Answer:
No
Step-by-step explanation:
All parallelograms are not a kite.
A kite is a quadrilateral with two disjoint pairs ( no side is in both pairs ) of equal-length, adjacent ( sharing a vertex ) sides. A parallelogram also has two pairs of equal-length sides, however they must be opposite, as opposed to adjacent.

is the same as, let say we have a value a.
[tex]a \times a \times a = - 343[/tex]
We know a negative multipled 3 times is negative so our answer is a negative.
a cube root of 343 is 7 so the cube root of -343 is -7.

If
f(x) = 2x + 1
and
g(x) = x - 3
f(g(x)) = 2x + ????
Answer:
f(g(x)) = 2x - 5Step-by-step explanation:
Given:
f(x) = 2x + 1and
g(x) = x - 3Find the composite function f(g(x)), substitute g(x) with its value:
f(g(x)) = f(x - 3) = 2(x - 3) + 1 = 2x - 6 + 1 = 2x - 5Answer:
It is given
4x+3y=24
We can also write it as
3y=24−4x
y=324−4x
Substituting x=0 in the given equation
y=324−4(0)
So we get
y=324
By division
y=8
Substituting x=3 in the given equation
y=324−4(3)
So we get
y=312

So I have this question I cannot figure out 3w+w2+1=10−w
Answer:
Answer: w is 1.6 or. -5.6
Step-by-step explanation:
• I guess the question asks to find the value of w
[tex]{ \rm{3w + {w}^{2} + 1 = 10 - w }}[/tex]
• arrange the equation in a quadratic equation format. i.e; ax² + bx + c = 0
[tex]{ \rm{ {w}^{2} + (3w + w) + 1 - 10 = 0 }} \\ \\ { \rm{ {w}^{2} + 4w - 9 = 0 }}[/tex]
• let's solve the equation using the quadratic formular
[tex] \hookrightarrow \: { \tt{w = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a} }} \\ [/tex]
a is 1b is 4c is -9• Substitute following the mathematical operation rules:
[tex]{ \rm{w = \frac{ - 4 \pm \sqrt{ {4}^{2} - (4 \times 1 \times - 9) } }{(2 \times 1)} }} \\ \\ { \rm{w = \frac{ - 4 \pm \sqrt{52} }{2} }}[/tex]
• split the result:
[tex]{ \rm{either \: \{w = \frac{ - 4 + \sqrt{52} }{2} \} \: \: or \: \: \{w = \frac{ - 4 - \sqrt{52} }{2} \} }} \\ \\ { \rm{either \: \{w = 1.6 \} \: \: or \: \: \{w = - 5.6 \}}}[/tex]
The total cost of a pizza and 3 drinks is $19. The price of the pizza is $10 and each drink is the same price, d. 6) Which model represents the situation?
The total cost of pizza and drinks, is an illustration of a linear function.
The model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]
The given parameters are:
[tex]\mathbf{Total =19}[/tex]
[tex]\mathbf{1\ pizza =10}[/tex]
[tex]\mathbf{1\ drink =d}[/tex]
The cost of 3 drinks will be 3d
The total cost would then be:
[tex]\mathbf{Total = 10 + 3d}[/tex]
Substitute 19 for Total
[tex]\mathbf{10 + 3d = 19}[/tex]
Rewrite the above equation as:
[tex]\mathbf{3d + 10 = 19}[/tex]
Hence, the model that represents the situation is: [tex]\mathbf{10 + 3d = 19}[/tex]
