Last week a jacket cost $39.50 this week the price of the jacket decreased by $4.50. What is the price of the jacket after the decrease how much would it cost to purchase 2 jackets this week ?
Answers
a) The cost price of the jacket after the decreased amount is $ 35
b) The cost price of 2 jackets is $ 70
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the price of the jacket after decrease be = A
Now , the equation will be
The original price of the jacket = $ 39.50
The amount decrease in the price of the jacket = $ 4.50
So , the cost price of the jacket after the decrease in price is = original price of the jacket - amount decrease in the price of the jacket
Substituting the values in the equation , we get
The cost price of the jacket = 39.50 - 4.50
The cost price of the jacket = $ 35.00
So , the cost price of the jacket is $ 35.00
Now , the cost price of 2 jackets is = 2 x sale price of the jacket
Substituting the values in the equation , we get
The cost price of 2 jackets is = 2 x 35
The cost price of 2 jackets is = $ 70
Therefore , The cost price of 2 jackets is $ 70
Hence ,
a) The cost price of the jacket after the decreased amount is $ 35
b) The cost price of 2 jackets is $ 70

Answer:
The recursive formula defines the sequence is .
Step-by-step explanation:
Three terms of an arithmetic sequence are
f(1) = 6
f(4) = 12
f(7) = 18
It means first term is 6, fourth term is 12 and seventh term is 18.
The formula for nth term of an arithmetic sequence is
where n is number of term, a is first term and d is common difference.
4th term of the AP is
Subtract 6 from both sides.
Divide both sides by 3.
The common difference is 2.
The recursive formula for an AP is
Substitute d=2 in the above equation.
It can be written as
Therefore the recursive formula defines the sequence is .
can also be written as

2/4 times 1/3=(2 times 1)/(4 times 3)=2/12
so to simplify, we find the ones exg 4/8=1/2 because 1/2 times 4/4=4/8 and 4/4 cancels out so
2/12=2/2 times 1/6
=1/6

To do this, we divide 12 by 5
12/5 = 2.4
2) Multiply 2.4 by 15
2.4 x 15 = 36
If you don't like decimals, you can also do it this way...
This can be rewritten as 15 x 1/5 x 12
Multiplications alone can be performed in any order
1) Work out what 1/5 of 15 is
1/5 of 15
15/5 = 3
2) 3 multiplied by 12
3 x 12 = 36
1/5 of 12 as much as 15 times = 36
Further Explanation:
The question given is an example of Number problems. Two major components of mathematical tools would be used to derive answers to similar problem like this. They are Multiplication and Division. Also the given question has an element of Fraction in it.
Fraction can be referred to as a number that has a part of a whole. It always has a numerator and denominator. Numerators are number values that are always on top, while denominators are number values that are always at the bottom. For example 2/4, 54/34
Multiplication can be defined as a process of multiplying several numbers to derive a particular number value(s). It is the process of adding numbers repeatedly in multiple folds. And two or more numbers are usually used to derive further values. And it is usually denoted as “times”. For example 2 x 3 = 6, 2 x 4 x 3 = 24
Division is the process of dividing or splitting number values into several equal parts. Of
Solution:
1 fifth of 12 can be written as 1/5 of 12, and can also be expressed as 1/5 x 12
Since 1/5 is a fraction, and must be multiplied by 12 then…
12 would be multiplied by 1, and then divided by 5 to get another number values
Therefore,
1/5 x 12 = 12/5
= 2.4
Recall 15 times as much as 1/5 of 12
Since 1/5 of 12 = 2.4
Therefore
15 x 2.4 = 36

Plug In The Numbers:
x^2 + 6^2 = 10^2
simplify
x^2 + 36 = 100
Next, Since Were Trying To Find X And Not C, We Subtract B From C Or 36 From 100
x^2 + 36 - 36 = 100 - 36
