What is the definition of variable in algebra?A symbol (often a letter) used in mathematics to represent an unknowable numerical value in such an equation or algebraic statement. A variable can be defined as a quantity that is changeable and not fixed. Variables are crucial since they make up a significant portion of algebra.Typically, "x" and "y" are used to express unknowable integers. However, it is not required; any letter will do.Example:
Consider the algebraic statement 2x + 6 as an example. In this case, the variable x is open to interpretation. If x = 1, the algebraic expression's value will be 2(1) + 6, or 8.To know more about the variable in algebra, here

Answer:
The volume of the ice cream cone is 528.1 cubic centimeters.
Step-by-step explanation:
The formula for finding the volume of a cone is V = [tex]\pi r^2\frac{h}{3}[/tex].
Substitute values now:
V = [tex]\pi* 5.8^2*\frac{15}{3}[/tex]
V ≈ 528.1
PQRS is a parallelogram with PQ=26cm and QR=20cm . If the distance between the longer-sides is 12.5cm , Find
Answer:
Below.
Step-by-step explanation:
I am guessing you want the area of the parallelogram.
Take the longer side to be the base.
Area = base * distance between base and opposite side
= 26 * 12.5
= 325 cm^2.

Write 125 x (5^4)7 as a single power of 5
125 x (5^4)7 as a single power of 5 is 28*5^4.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Given;
125 x (5^4)7
Now, 125 x (5^4)7
=125x140
=17500
=28*5^4
Therefore, by algebra the answer will be 28*5^4.

Paulette wrote the equation below to show f, the amount of framing she needs for a square frame with a side length of s centimeters. f=4s How many centimeters of framing does Paulette need for a square frame that has a side length of 15.3 centimeters. Pls help this is a test A. 61.2 centimeters B. 60.3 centimeters D. 19.3 centimeters C. 11.3 centimeters
Answer: 61.2 centimeters
Step-by-step explanation:
Since the equation given to show the amount of framing that she needs for a square frame with a side length of s centimeters is:
f = 4s
Therefore, the number of centimeters of framing needed by Paulette for a square frame that has a side length of 15.3 centimeters will be:
f = 4s
f = 4 × 15.3
f = 61.2 centimeters

In October sally drove 560 miles in her car.
the car travelled 34.5 miles for each gallon of petrol used
Petrol cost £1.08 per litre.
1 gallon = 4.55 litres.
Work out the cost of the petrol the car used in October
The cost of petrol the car used in October is;
Amount spent on fuel in October = £79.76
Distance sally drove in October = 560 miles
She used 1 gallon of petrol for every 34.5 miles she drove.
Thus, number of gallons of petrol she used for the month of October on the car = 560/34.5 gallons
Now, we are told that;
1 gallon = 4.55 litres
Thus; 560/34.5 gallons = (560/34.5) × 4.55/1
Quantity of petrol she used for the month in liters = 73.855 litres
Petrol costs £1.08 per liter.
Thus;
Amount spent on fuel in October = 1.08 × 73.855
Amount spent on fuel in October = £79.7634 ≈ £79.76

London in column bought 1/2 pound of peanuts they are sharing the nuts equally how many pounds of nuts do each person get
Answer: 1/4 pounds
Step-by-step explanation:
Full question is:
Landon and Colin bought a 1/2 pound of peanuts. They are sharing the nuts equally. How many pounds of peanuts will each person get?
There are 2 people here - London and Colin - and they are to share 1/2 pounds of nuts equally amongst themselves.
They should therefore divide the nuts in 2:
= Amount of nuts / Number of people
= 1/2 ÷ 2
= 1/2 * 1/2
= 1/4 pounds
Note: When dividing a fraction, multiply the inverse of the divisor.

Cendrick D'Amitrano works Friday and Saturday delivering pizza. He delivers 8 pizzas on Friday. How many pizzas must he deliver on Saturday to average (mean) 11 pizzas per day?
Answer:
Number of pizza deliver on Saturday = 14 pizza
Step-by-step explanation:
Given:
Number of delivery day (Friday, Saturday) = 2
Number of pizza deliver on Friday = 8
Average of delivery (Mean) = 11 pizza
Find:
Number of pizza deliver on Saturday
Computation:
Mean = Sum of pizza / Number of delivery day
11 = [8 + Number of pizza deliver on Saturday] / 2
22 = 8 + Number of pizza deliver on Saturday
Number of pizza deliver on Saturday = 22 - 8
Number of pizza deliver on Saturday = 14 pizza

f(7)=
g(7)=
The equation for f(x) is
The equation for g(x) is
Answer: f(7) = -128
g(7) = 26
Equation of f(x): f(x)= -11x-51
Equation of g(x): g(x)=3x+5
Step-by-step explanation:
Rate of change of a function: [tex]\dfrac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]
From the table. Rate of change in f(x)= [tex]\dfrac{f(1)-f(0)}{1-0}=\dfrac{-62+51}{1}=-11[/tex]
Rate of change in g(x)= [tex]\dfrac{g(1)-g(0)}{1-0}=\dfrac{8-5}{1}=3[/tex]
Also, the rate of change throughout the function is the same, hence both are linear functions.
Equation of linear function: [tex]f(x)=mx+c[/tex], where m= rate of change of function, c = f(x) at x=0.
From table, f(0)= -51 , g(0)=5
Equation of f(x): f(x)= -11x-51
Equation of g(x): g(x)=3x+5
f(7) = -11(7)-51 = -77-51 = -128
g(7) = 3(7)+5 = 21+5 = 26
f(7) = -128
g(7) = 26
