The proof shows that f1+ f3 +f5+ ... +f2n-1=f2n, Fibonacci number. This can be proven by using mathematical induction and manipulating the algebraic expression for the sum and the Fibonacci sequence.
We can prove this by mathematical induction.
Base case: When n = 1, the equation becomes f1 = f2 which is true.
Inductive step: Assume that the equation holds true for some value k, i.e., f1 + f3 + f5 + ... + f2k-1 = f2k.
We need to prove that the equation holds true for k+1, i.e., f1 + f3 + f5 + ... + f2(k+1)-1 = f2(k+1).
Adding f2k+1 to both sides of the equation for k, we get
f1 + f3 + f5 + ... + f2k-1 + f2k+1 = f2k + f2k+1
Now, we can use the identity that f2k+1 = f2k + f2k-1, which comes from the definition of the Fibonacci sequence. Substituting this, we get
f1 + f3 + f5 + ... + f2k-1 + f2k + f2k-1 = f2k + f2k+1
Rearranging and simplifying, we get
f1 + f3 + f5 + ... + f2k+1 = f2k+2
Therefore, the equation holds true for k+1 as well.
By the principle of mathematical induction, the equation holds true for all positive integer values of n. Hence, we have proved that f1 + f3 + f5 + ... + f2n-1 = f2n.

Priya is making burgers for a party. She has 5 pounds of meat and uses 1/3 of a pound for one burger. How many burgers can priya make?
Answer: Priya can make 15 burgers with 5 pounds of meat
Step-by-step explanation:
Step 1
From Priya's receipe,
1 burger can be made from 1/3 of a pound of meat
How many burgers can be made from 5 pound of meat
Step 2 Using the equation below, that
1 burger = 1/3 pound of meat
Therefore 5 pounds of meat
5 x 1 / 1/3 = 5/(1/3)
= 5 x3 = 15 Burgers.

The cereal box shown below is a rectangular prism. Find the surface area of the cereal box.
Answer:
580 cm^2
Step-by-step explanation:
First, find the area of the front and back. 20*10=200
There are 2 sides with 20*10 ( front and back) so we can multiply by 2. 200*2=400
Then, the sides. 3*20=60*2=120
Then, the top and bottom 10*3=30*2=60
400+120+60=580
Answer:
420
Step-by-step explanation:

Simplify (4y - 3x - 2) - (7y + 4x + 3)
Answer:
-7x - 3y -5
Step-by-step explanation:
Answer:
-7x - 3y - 5
Step-by-step explanation:
In this question, you will simplify the expression given.
Solve:
(4y - 3x - 2) - (7y + 4x + 3)
Use the distributive property.
4y - 3x - 2 - 7y - 4x - 3
Combine like terms.
4y - 3x - 2 - 7y - 4x - 3
-7x + 4y - 2 - 7y - 3
-7x - 3y - 2 - 3
-7x - 3y - 5
Since we can't simplify further, your final answer would be -7x - 3y - 5
Solve for x:
(a) 4x - 21 = 5 - 9x
Answer:
X = 2
Step-by-step explanation:
First we'll need to simplify this equation:
Add 9x on both sides:
13x - 21 = 5
Add 21 on both sides:
13x = 26
Divide 26/13
26/13 = 2
X=2
(You can check this yourself by plugging x into the equation)

25% of that amount
How much did each person pay if they shared the price of lunch and the tip equally?
Answer:
$37.50
Step-by-step explanation:
$60 x .25 = $15 (tip)
$60 (meal) + $15 (tip) = $75
$75 ÷ 2 (# of people splitting the cost) = $37.50

Answer:
We'll need 2 points so we'll choose (-6, 0) and (0, -3).
Let's calculate the slope (or 'm') using
Slope or m = (Y2 -Y1) ÷ (X2 -X1)
Slope ('m') = (-3 -0) / (0, - -6) = -3 / 6 = -1/2
Then we calculate the equation using:
(y - y1) = m • (x -x1)
(y - 0) = -1/2 * (x - -6)
y = -1/2 x -3

Step-by-step explanation:
Answer:
x + 2y = - 6Step-by-step explanation:
X-intercept: (-6, 0)
Y-intercept: (0, -3) ⇒ b = -3
Slope: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{0+3}{-6+0}=-\dfrac12[/tex]
Slope-intercept form y = mx + b
[tex]y=-\frac12x-3[/tex] {multiply both sides by 2}
2y = - x - 6 {add x to both sides}
x + 2y = - 6

For the inverse variation equation p=8/v what is the value of V when p = 4?
O 1/8
o 1/2
O 2
O 32
Answer:
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form
y*x=k or y= k/x
in this problem we have that
the value of the constant K is equal to 8
so
pv=8
Solve for V
v=8/p
Find the value of V for p=4
substitute the value of P in the formula
v=8/4=2
therefore
the answer is
the value of V is equal to 2

Solve 3(x + 1) + 6 = 33
Answer:
3(X+1)+6=33
3x+3+6=33
3x+9=33
3x=33-9
X=24/3
X=8
Answer:
[tex]x = 8[/tex]
Step-by-step explanation:
1) Subtract 6 from both sides.
[tex]3(x + 1) = 33 - 6[/tex]
2) Simplify 33 - 6 to 27.
[tex]3(x + 1) = 27[/tex]
3) Divide both sides by 3.
[tex]x + 1 = \frac{27}{3} [/tex]
4) Simplify 27/3 to 9.
[tex]x + 1 = 9[/tex]
5) Subtract 1 from both sides.
[tex]x = 9 - 1[/tex]
6) Simplify 9 - 1 to 8.
[tex]x = 8[/tex]
Therefor the answer is, x = 8.
