The world record for most selfies taken by a person in one hour is calculated to be 1449.
The world record for the most selfies taken by one person in one hour can be determined by using an algebraic expression.
As 4296 is 51 fewer than three times the World record for the most selfies taken by one person in one hour, we can consider x to be the world record by which we get an algebraic expression as follows;
3x - 51 = 4296
Solving for x;
3x = 4296 + 51
3x = 4347
x = 4347 / 3
x = 1449
Therefore, 1449 is calculated to be the world record for most selfies by one person in one hour.

The jumbo cans of frosting would she need to frost 280 cupcakes is 8 cans.
What is addition?Addition simply means the sum of the numbers that are given.
In this case, Bette used 3 jumbo cans of frosting to frost 105 cupcakes for the cupcake challenge at her school and 5 jumbo cans of frosting to frost an additional 175 cupcakes. This implies that the total cupcakes will be:
= 105 + 175 = 280
In this case, the cans used will be the addition of the cans above. This will be:
= 3 + 5
= 8 cans

The number of ounces of fruit and number of ounces of nuts that will meet the requirement with the least amount of calories is
3 ounces of nut5 ounces of fruitThe least number of calorie is 250 calories
How to find the number of ounces of fruit and number of ounces of nuts with the least amount of calories.given data
1. each ounce of fruit will supply zero units of protein, 3 units of carbohydrates, 2 units of fat and will contain 20 calories
2. each ounce of nuts will supply 3 units of protein, 2 units of carbohydrates and 4 units of fat, and will contain 50 calories
3. Every package must provide at least 9 units of protein, at least 18 carbohydrates, and no more than 22 units of fat
To get at least 9 units of protein, we take at least 3 ounces of nut
3 ounces of nut will give 3 times each unit, and they are as follows
3 * 3 = 9 units of protein2 * 3 = 6 units of carbohydrates4 * 3 = 12 units of fat50 * 3 = 150 caloriesAnother restriction is no more than 22 units of fat and we have 12 already remaining 10 units of fat
fruits has lesser calories hence we use it to get the required fats
10 units of fat ÷ 2 units of fat in fruit = 5
5 ounces of fruit will give 5 times each unit, and they are as follows
5 * 3 = 15 units of carbohydrates5 * 2 = 10 units of fat 5 * 20 = 100 caloriesCombining 3 ounces of nut and 5 ounces of fruit will give
9 + 0= 9 units of protein6 + 15 = 21 units of carbohydrates12 + 10 = 22 units of fat150 + 100 = 250 caloriesAbove maintains the requirements stated in the question with the minimal calorie

How to solve the blank
Answer:
blank = - 3
Step-by-step explanation:
let x represent the blanks , then
[tex]\frac{2}{3}[/tex] ([tex]\frac{9}{5}[/tex] + x) = [tex]\frac{2}{5}[/tex] x + [tex]\frac{2}{5}[/tex]
multiply through by 15 ( the LCM of 3 and 5 ) to clear the fractions
10([tex]\frac{9}{5}[/tex] + x) = 6x + 6 ← distribute parenthesis on left side
[tex]\frac{90}{5}[/tex] + 10x = 6x + 6
18 + 10x = 6x + 6 ( subtract 6x from both sides )
18 + 4x = 6 ( subtract 18 from both sides )
4x = - 12 ( divide both sides by 4 )

We have -
y = f(x) = [tex]\sqrt{11x+12}[/tex]
We have to find its inverse function.
What is the procedure to find inverse of function ?Inverse of a function can be calculated by following the steps mentioned below -
Step 1 - Replace 'y' with 'x' and vice - versa.
Step 2 - Rewrite the equation by solving for 'y'.
Step 3 - Replace 'y' with f⁻¹(x).
According to the question -
y = f(x) = [tex]\sqrt{11x+12}[/tex]
x = [tex]\sqrt{11y+12}[/tex]
x² = 11y + 12
x² - 12 = 11y
y = (x² - 12)/11
f⁻¹(x) = (x² - 12)/11

A linear equation is a mathematical form of a line segment the point (6,5) satisfies the equation y = 2/3x + 1 so it is the solution of the equation but (9,8) is not the solution.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
As per the given linear equation, y = 2/3x + 1
To be a point of its solution the point must satisfy the given equation.
Substitute (6,5)
5 = (2/3)6 + 1
5 = 2(2) + 1 = 5
Therefore, the (6,5) is the solution of the equation.
Substitute,(9,8)
(2/3)9 + 1 = 7
8 ≠ 7
So,(9,8) is not the solution of the equation.
