The expression of the total cost of clothes will be 20 + j.
What is Algebra?
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The amount you spend if you buy a shirt for $20 and jeans for j dollars.
Then the expression of the total cost of clothes.
The expression is given as the sum of the cost of the shirt and the cost of the jeans.
Then the expression will be
⇒ $20 + $j
⇒ 20 + j
The expression of the total cost of clothes will be 20 + j.

Answer:
Step-by-step explanation:
Given :
We have to write which identity we will use to prove the given statement.
Consider
Take left hand side of given expression
We know
Comparing , we get, a= 180° and b = q
Substitute , we get,
Also, we know and
Substitute, we get,
Simplify , we get,
Hence, use difference identity to prove the given result.
First you would use the sum and difference formula of
cos(a – b) = cos(a)cos(b) + sin(a)sin(b) because you have a difference inside the parentheses for cosine.
Hope this helps.

C. a rotation 180° clockwise about the origin followed by a reflection across the line y = x
Step-by-step explanation:
Let us assume that the coordinate of A in triangle ABC is A(x, y)
A) If there is a reflection across line y = x, the new coordinate is at A'(y, x).
If a reflection across the line y = -x is then followed, the new coordinate is at A"(-x, -y)
B) If there is a reflection across line x axis, the new coordinate is at A'(x, -y).
If a reflection across the line y axis is then done, the new coordinate is at
A"(-x, -y)
C) If there is a rotation 180° clockwise about the origin, the new coordinate is at A'(-x, -y).
If a reflection across the line y = x is then followed, the new coordinate is at A"(-y, -x)
D) B) If there is a reflection across line y axis, the new coordinate is at A'(-x, y).
If a reflection across the line x axis is then done, the new coordinate is at
A"(-x, -y)
Since only option C has a different result from the remaining options, hence option C would not five triangle A'B'C'

The value of WZ in the given similar polygons, is 72
What are similar polygons?
When polygons are similar their corresponding angles are congruent and their corresponding sides are proportional.
Given that, quadrilateral ABCD and quadrilateral WXYZ are similar,
The order of the proportionality statement tells us which angles and sides are corresponding.
To solve, set up a proportion.
AD/WZ = DC/ZY
12/WZ = 6/36
Cross multiply.
6(WZ) = 12x36
6(WZ) = 432
Divide both sides by 6
WZ = 72
Hence, the value of WZ is 72

5(10) = 50 + 3 = 53 - numerator, denominator stays the same
53/10 - answer
Final answer:
To write 5 3/10 as an improper fraction, convert the whole number to a fraction and add the fractional part. Therefore, 5 3/10 as an improper fraction is 53/10.
Explanation:
To write 5 3/10 as an improper fraction, we first convert the whole number to a fraction by multiplying it by the denominator of the fractional part. In this case, 5 * 10 = 50. So, the whole number 5 can be written as the fraction 50/10. Then, we add the fractional part, which gives us 53/10. Therefore, 5 3/10 as an improper fraction is 53/10.
