What is Equation Modelling?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is that we have rewritten -
(1/7)ˣ ⁻ ² - (1/7)ˣ as [A] x (1/7)ˣ
We have (1/7)ˣ ⁻ ² - (1/7)ˣ rewritten as [A] x (1/7)ˣ. So, we can write -
(1/7)ˣ ⁻ ² - (1/7)ˣ = [A] x (1/7)ˣ.
Now, we can write [(1/7)ˣ ⁻ ² - (1/7)ˣ] as :
[(1/7)ˣ / (1/7)²] - (1/7)ˣ
(1/7)ˣ [1/(1/7)² - 1]
We have -
(1/7)ˣ ⁻ ² - (1/7)ˣ = [A] x (1/7)ˣ.
So, we can write -
(1/7)ˣ × [1/(1/7)² - 1] = [A] × (1/7)ˣ.
On comparing, we get -
[A] = [1/(1/7)² - 1]
[A] = 48
Therefore, the value of [A] will be 48.

What is the solution to the equation: 37x=9x+4
Answer: X = 1/7
Step-by-step explanation:
37x = 9x + 4
subtract 9x to both sides
28x = 4
now divide by 28
x = 4/28
simplified its
x = 1/7
Answer:
28x=4
x=1/7
Step-by-step explanation:
First you would make simplyfiy the expression so that you would have x on one side, when you do that you will get 28x=4. When simplyfied you will get 1/7.

The rectangle is 16 inches by 25 inches. If the scale is 4 in :5 ft what is the length and width of the rectangle in feet.
Answer:
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.
Step-by-step explanation:
Let the scale be [tex]4\,in\,:\,5\,ft[/tex] and the dimensions of the rectangle being 4 inches and 5 inches, respectively. The scale ([tex]r[/tex]), measured in inches per feet, is equivalent to the following rational number:
[tex]r = \frac{4\,in}{5\,ft}[/tex]
We can convert each length by dividing it by scale factor. That is:
Length
[tex]l' = \frac{16\,in}{\frac{4\,in}{5\,ft} }[/tex]
[tex]l' = 20\,ft[/tex]
Width
[tex]w' = \frac{25\,in}{\frac{4\,in}{5\,ft} }[/tex]
[tex]w' = 31.25\,ft[/tex]
The length and width of the rectangle are 20 feet and 31.25 feet, respectively.

3 cups of tea and 4 cups of coffee costs £3.45 in total.
4 cups of tea and 1 cup of coffee costs £2.65 in total.
How much would it costs to buy one cup of each in total?
Answer:
A) 3T + 4C = 3.45
B) 4T + 1C = 2.65 We'll multiply this by -4
B) -16T -4C = -10.60 then we'll add A)
A) 3T + 4C = 3.45
-13T = -7.15
Tea is .55
and coffee is
A) 3 * .55 + 4C = 3.45
4C = 3.45 -(3 * .55)
4C = 1.80
coffee is .45

in a sequence of numbers, a3=3, a4=7, a5=11, a6=15, and a7=19. based on this information, which equation can be used to find the nth term in the sequence, an?
Answer:
Step-by-step explanation:
sequence is a1,a2,a3,a4,a5,a6,a7,...
or a1,a2,3,7,11,15,...
d=a4-a3=7-3=4
a3=a1+(3-1)d
3=a1+2d
3=a1+2×4
a1=3-8=-5
an=a1+(n-1)d
an=-5+(n-1)4
an=-5+4n-4

The triangle represents a scale drawing that was created by using a factor of One-half.
A triangle with sides lengths of 5 inches.
Which is true of the measures of the sides of the original triangle?
Each side of the original triangle is One-half the length of each side of the scale drawing.
Each side of the original triangle is 2 times the length of each side of the scale drawing.
Each side of the original triangle is the same length as each side of the scale drawing.
Each side of the original triangle is 2 inches shorter than the scale drawing.
9514 1404 393
Answer:
(b) Each side of the original triangle is 2 times the length of each side of the scale drawing.
Step-by-step explanation:
If the smaller is 1/2 the larger, then the larger is 2 times the smaller. The original triangle's sides are 2 times those of the scale drawing.
If Brian took the same test and received a score of 80 % how many questions did he get right? ( hint the test is out of 20 points )
Answer:
16
Explanation:
First you convert
80
%
into a decimal which is
.80
then you multiply it by
20
.
.80
×
20
=
16
We multiply it by
20
because that's our total and by
.80
because that's the amount that we got correct. Had it been
100
%
then that would mean we got every question right.

Hey there!
The answer to your question is [tex]-6+4p[/tex]
Given:
[tex]-(6-4p)[/tex]
First, we distribute the negative sign to both terms ([tex]6[/tex] [tex]and[/tex] [tex]-4p[/tex]) This would make the [tex]6[/tex] negative and the [tex]-4p[/tex] positive, so we have:
[tex]-6[/tex] [tex]and[/tex] [tex]4p[/tex]
Add them together and we get:
[tex]-6+4p[/tex]

Alfie has £10 note He buys 3 pens costing 1.45 each and some pencils costing 90p He gets 2.05 change. How many pencils did he buy?
Answer:
4 pencils
Step-by-step explanation:
Note= pencils costing 0. 90p
Given data
Balance= £10
pen= 3*1.45= £4.35
pencils=0.90p
change= £2.05
2.05= 10-4.35-90p
solve for p
2.05= 5.65-90p
collect like terms
5.65-2.05= 0.90p
3.6=90p
divide both sides by 90
p=3.6/0.90
p=4
