A variable in mathematics is a sign and placeholder for any mathematical object (from the Latin variabilis, "changeable"). A variable can specifically represent a number, a vector, a matrix, a function, its argument, a set, or one of its elements.
A variety of issues are resolved by algebraic calculations that treat variables like explicit integers in a single computation. The quadratic formula, for instance, can be used to solve any quadratic equation by exchanging the variables in the quadratic formula for the numerical values of the coefficients in the equation.

The sidewalk around a lake is 9/10 mile long. You walk 3 laps Around the lake in the morning and 2 laps in the evening. Your friend walks the same total distance as you on a 1 1/2 mile track. How many laps does your friend walks?
Answers
The total laps your friend runs is 3.
How many laps does your friend run?A fraction is a non-integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below.
A proper fraction is a fraction where the numerator is less than the denominator. A mixed fraction is a fraction that is made up of a whole number and a proper fraction.
The first step is to determine the total miles you run
Total miles run = length of the side walk x total number of laps
9/10 x (3 + 2)
9/10 x 5 = 45 / 10 = 4.5 miles
The second step is to determine the total number of laps she runs:
4.5 miles / 1 1/2 miles

9. The graph represents the path of a football kicked by a player, where x is the horizontal
distance (in yards) and y is the height (in yards). The player kicks the ball a second time
so that it travels the same horizontal distance, but reaches a maximum height that is 6
yards greater than the maximum height of the first kick. Write a function that models
the path of the second kick.
y=-0.02(x - 30)2 + 18
Answers
The function that models the path of the second kick is y = -0.02(x - 0.30)^2 + 24
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to write a function that models the path of the second kick?The function that models the path of the first kick is given as
y = -0.02(x - 0.30)^2 + 18
A quadratic function is represented as
y = a(x - h)^2 + k
Where
Vertex = (h, k)
In this case, the interpretation of the vertex is
Vertex = (Horizontal distance, Maximum height)
Using the above as a guide, we have
Vertex = (30, 18)
This means that
Horizontal distance = 30
Maximum height = 18
For the second ball, we have
Same horizontal distanceMaximum height is 6 yards greater than the maximum height of the first kickThis means that
Horizontal distance = 30
Maximum height = 18 + 6
Evaluate
Horizontal distance = 30
Maximum height = 24
So, the function that models the path of the second kick is y = -0.02(x - 0.30)^2 + 24
Hence, the function that models the path of the second kick is y = -0.02(x - 0.30)^2 + 24

(x-5)/3=21 What is equal to x
Answers
Answer: x=68
Step-by-step explanation:
(x-5)/3=21
(x-5)*3/3=21*3 ==> Multiply both sides by 3 to remove fractions
x-5=21*3
x-5=63
x+5-5=63+5 ==> Add 5 on both sides to isolate the x variable
x=63+5
x=68
Let's solve the problem,
→ (x - 5)/3 = 21
→ x - 5 = 21 × 3
→ x = 63 + 5
→ [ x = 68 ]
Hence, the value is 68.

Consecutive integers are integers that come after each other. We want to find two consecutive even integers that when added give us 46.
Let the first consecutive even integer be x. Since even integers come every 2 integers (even, odd, even), the second even integer should be x + 2.
Solve for xx + x + 2 = 462x + 2 = 462x = 44x = 22That means x + 2 should be 24.

Answers
If total revenue given by the function R=16.5x and has total cost given by C=14x+400, where x is the number of items produced and sold then the number of units that gives break even for the product is 160.
What is function?In mathematics, a function is an expression, rule, or law that specifies a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are commonplace in mathematics and are required for expressing physical relationships in the sciences. The present concept of function was proposed by German mathematician Peter Dirichlet in 1837.
If a variable y is so tied to a variable x that there is a rule that determines a unique value of y whenever a numerical value is assigned to x, then y is referred to as a function of the independent variable x.
If the manufacturer will break even for the products then
Revenue = Cost
F(R) = F(C)
14x+400 = 16.5x
On solving the equation
16.5x - 14x = 400
2.5x = 400
x = 400/2.5
x = 160
In the graph the value of x is 160 as well

Answers
Answer: 17 strings
Step-by-step explanation:
let the number of strings be a
let the number of beads on each string be b
a − b = 10 (first equation)
a × b = 119 (second equation)
From the first equation:
a = 10 + b
substitute first equation into second equation
b × (10 + b) = 119
10b + b² − 119 = 0
b = 7 or b = -17 reject -17
