Answer:
(5 × 4) - 13 = 7
Step-by-step explanation:
Given that,
→ n = 5
Let's solve the problem,
→ x = n × 4
→ x = 5 × 4
→ [ x = 20 ]
Then 13 less than the product will be,
→ x - 13
→ 20 - 13 = 7
Therefore, the solution is 7.

Step-by-step explanation:
A flagpole casts a shadow that is 50 feet long. At the same time, a woman standing nearby who is 6 feet tall casts a shadow that is 3 ft long. How tall is the flagpole?
The height of the flagpole is 100 feet.
What are shadows?Shadows are area devoid of light as a result of the obstruction of light by an opaque object.
Analysis:
The length of the shadow and the height of the flagpole are at right angles.
Similarly, the height of the woman and the length of her shadow are at right angles. Making both similar right-angled triangles.
The ratio of the height of the woman to that of pole is equal to ratio of the length of woman's shadow to that of the flagpole.
let length of flagpole be h.
height of woman = 6 feet
length of shadow of woman = 3 feet
length of shadow of pole = 50 feet.
[tex]\frac{6}{h}[/tex] = [tex]\frac{3}{50}[/tex]
3h = 300
h = 100 feet
In conclusion, the height of the flag pole is 100 feet.

Mr frank bought 6 pounds of grapes and 3 pounds of apples in the store. he paid $28.20 for the whole purchase. his neighbor mrs. bland pain $16.90 for 2 pounds of grapes and 4 pounds of apples. if all of the apples in the store cost the same and all grapes cost the same, what is the price of one pound of grapes?
The price of one pound of grapes and one pounds of apples in the store is $3.45 and $2.5 respectively.
Simultaneous equationlet
x = price of grapesy = price of apples6x + 3y = 28.20
2x + 4y = 16.90

A car used 12 gallons to travel 288 miles. How many gallons of gas will the car use to travel 192 miles?
12x + 288y = 0 -->(i) x + 192y = 0
=> 12(x + 192y) = 0 × 12
=> 12x + 2304y = 0 -->(ii)
By Elimination method,Equation (i) - (ii)(12x + 288y) - (12x + 2304y) = 0 - 0
=> 12x + 288y - 12x - 2304y = 0
=> - 2016y = 0
=> y = 2016
Putting the value of "y" in Equation (i)12x + 288y = 0
=> 12x + 288 × 2016 = 0
=> 12x + 580608 = 0
=> 12x = - 580608
=> x = 48384

Leanne and her family plan to attend a symphony at an orchestra hall. Before booking the tickets, Leanne checked a website where visitors rated the view of the symphony's soloist from their seating section. The data from the website is summarized in the table.
Section Number of reviewers who sat in the section Number of reviewers who rated the view as "perfect"
L1 90 57
L2 52 33
L3 75 47
U1 84 55
U2 43 27
U3 35 22
According to the data from the website, in which seating section should Leanne's family book the tickets if they want to maximize their chances of having a "perfect" view of the symphony's soloist?
Using proportions, it is found that Leanne's family should book their tickets at Section U1 to maximize their chances of having a "perfect" view.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, the section with the highest proportion of perfect views should be chosen, hence:
pL1 = 57/90 = 0.633
pL2 = 33/52 = 0.635
pL3 = 47/75 = 0.623
PU1 = 55/84 = 0.655
pU2 = 27/43 = 0.628
pU3 = 22/35 = 0.629
Leanne's family should book their tickets at Section U1 to maximize their chances of having a "perfect" view.

The equivalent value of x from the equation is x = 2
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
In an equation, the expressions on either side of the equals sign are called the left-hand side (LHS) and the right-hand side (RHS), respectively. The equals sign (=) indicates that the two expressions have the same value, and that the equation is true for certain values of the variables involved.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. It typically consists mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.
Given data ,
Let the equation be represented as A
Now , the value of A is
8 = 2x + 4
On simplifying the equation , we gt
Subtracting 4 on both sides , we get
2x = 8 - 4
2x = 4
Divide by 2 on both sides , we get
x = 2
Therefore , the value of x is 2
Hence , the equation is solved and x = 2
