Mr. Washington drills a water well. Ground conditions cause an increase of 5% to the cost per meter, c. In addition, the cost of equipment is $1,400. He calculates the cost of his well using the expression 1, 400 + 1.05c . What other expression could he have used?
Answers
Explanation:
c and 0.05c are like terms, so they can be simplified to be 1.05c. Therefore, c + 0.05c + 1400 = 1.05c + 1400.

A car used 12 gallons to travel 288 miles. How many gallons of gas will the car use to travel 192 miles?
Answers
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
Hope it helpsMr 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?
Answers
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
multiply equation (2) by 36x + 3y = 28.20
6x + 12y = 50.70
subtract the equation9y = 22.50
y = 22.50/9
y = $2.5
substitute y into (2) in
2x + 4y = 16.90
2x + 4(2.5) = 16.90
2x + 10 = 16.90
2x = 16.90 - 10
2x = 6.90
x = 6.90/2
x = $3.45

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?
Answers
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

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?
Answers
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.

One year, the population of a city was 73,000. Several years later it was 85,410. Find the percentage decrease
Answers
The percentage decrease is 14.52% if, one year, the population of a city was 73,000. Several years later, it was 85,410.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
The initial population = 85410
The final population = 73000
The decrease = (85410 - 73000)/85410 = 0.1452
The percentage decrease = 0.1452×100 = 14.52%
Thus, the percentage decrease is 14.52% if one year, the population of a city was 73,000. Several years later, it was 85,410.

Here is a diagram and its corresponding equation. Find the solution to the equation. Tape diagram, 4 parts labeled x + 7, total 38. 4(x+7)=38
Answers
The distribute multiplication property allows us to multiple the 4 by the “x” and the 4 by the 7.
This brings us to
4x +28 = 38
Now we must subtract the 28 to the 38 in order to begin getting the “x” by itself.
4x = 10
Now divide by 4 to fully get the X alone
4x/4 = 10/4
x= 10/4 = 5/2 = 2 1/2
