Answer:
Blouse = $13.00
Jeans = $25.50
Step-by-step explanation:
x = blouse
y = jeans
x + y = 38.5
y = x + 12.5
Use substitution:
x + x + 12.5 = 38.5
2x = 26
x = 13
Blouse = $13.00
Jeans = $25.50
The price of Blouse is $13.00 and price of Jeans is $25.50.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let x represents the price of blouse and y represents the price of jeans.
mary bought a blouse and a pair of jeans for 38.50
x+y=38.5
jeans cost 12.50 more then the blouse
y=12.5+x
We need to find the price of jeans.
Substitute y value in above equation.
x + x + 12.5 = 38.5
Add the like terms
2x+12.5 = 38.5
Subtract 12.5 on both sides
2x = 26
Divide both sides by 2
x = 13
Hence, the price of Blouse is $13.00 and price of Jeans is $25.50.

HELP WITH GEOMETRY PLSSS
Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 10 people took the trip. She was able to purchase coach tickets for $230 and first class tickets for $1290. She used her total budget for airfare for the trip, which was $7600. How many first class tickets did she buy? How many coach tickets did she buy?
You can set up a system of equations for this problem. Let x = number of coach tickets and y = number of first class tickets. Then:
330x + 1220y = 12730 (cost of coach tickets plus cost of first class tickets is total budget)
x + y = 17 (number of coach tickets plus number of first class tickets is total number of people)
Solve the second equation for y to get y = 17 - x, then plug that into the first equation and solve for x:
330x + 1220(17 - x) = 12730
330x + 20740 - 1220x = 12730
-890x + 20740 = 12730
-890x = -8010
x = 9
Sarah bought x = 9 coach tickets. Plug that into the second equation and solve for y:
9 + y = 17
y = 8
Sarah bought y = 8 first class tickets.

The function
has the same amplitude as the function y = cos(x – 4) + 1.
The function
is a translation of the parent cosine function.
Answer: the function y = cos(2x) - 2 and the function y = cos(x) - 3
Step-by-step explanation: just took it
Function [tex]y=cos2(x)-2[/tex] and function [tex]y=cos(x)-3[/tex].
Function:A function in mathematics from a set [tex]x[/tex] to a set [tex]y[/tex] allocates exactly one element [tex]y[/tex] to each element [tex]x[/tex]. The sets [tex]x[/tex] and [tex]y[/tex] are collectively referred to as the function's domain and codomain, respectively.Initially, functions represented the idealized relationship between two changing quantities. A planet's position, for instance, depends on time. In the past, the idea was developed with the infinitesimal calculus at the end of the 17th century, and the functions that were taken into consideration until the 19th century were differentiable (that is, they had a high degree of regularity).Solution -
The function which has the same amplitude as the function [tex]y=cos(x-4)+1[/tex] and is the translation of the parent cosine is as follows:
[tex]y=cos2(x)-2[/tex][tex]y=cos(x)-3[/tex]Therefore, function [tex]y=cos2(x)-2[/tex] , and function [tex]y=cos(x)-3[/tex].

Find the slope of a line parallel and perpendicular to the line with given coordinates: (7, -2) and (1, -3).
Answer:
[tex]m=\frac{1}{6}[/tex] (Parallel)
[tex]m=-6[/tex] (Perpendicular)
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in the 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{-3-(-2)}{1-7}[/tex]
[tex]m=\frac{-3+2}{-6}[/tex]
[tex]m=\frac{-1}{-6}[/tex]
[tex]m=\frac{1}{6}[/tex]
A parallel line always has the same slope as the original.
[tex]m=\frac{1}{6}[/tex] (Original)
[tex]m=\frac{1}{6}[/tex] (Parallel)
A perpendicular line always has the negative reciprocal slope of the original.
[tex]m=\frac{1}{6}[/tex] (Original)
[tex]m=-6[/tex] (Perpendicular)
A Sand dune stands 5 feet above sea level. the hill is eroding at a rate of 1 foot per 20 years. let y represent the height of the sand dune after x years. which equation represents the situation
Answer:
5 - (1 + 20) = yx
Step-by-step explanation:
So if 5ft is the original height, we would need to distribute that to decrease in the following years. That is where the 5 - comes from. Next we know that is it is eroding 1 foot in 20 years so that is 5- (1+20) You HAVE to distribute that and not add. Then it equals y the height of the dune in x, the years. Honestly 5 feet above sea level is kinda puny for a sand dune ;P.

The width of a rectangle is 9 cm less than twice the length. the perimeter is 72 cm. What is the length and width
9 times 9=72
Step-by-step explanation:
if if the width is 9 then the length is 9 because 9 times 9 equals 72
Answer:
The length is 15
The width is 21
Step-by-step explanation:
Say the length of the rectangle is x.
Then, the width would be 2x-9.
You can use this to make the equation
x+x+2x-9+2x-9=72
6x-18=72
6x=90
x=15
2x-9=30-9=21
Therefore,
The length is 15
The width is 21

x = 72
Step-by-step explanation:
The sum of interior angles of a pentagon is (5-2)(180°) = 3·180°. The sum of the two right angles is 180°, so we can write the equation ...
180° +2x° +x° +2x° = 3·180°
5x = 2·180 = 360 . . . . divide by °, subtract 180
x = 360/5 = 72 . . . . . . divide by 5
The value of x is 72.
