A pair of pants cost 50% more than a tie. A shirt cost 25% more than the same tie. By what percentage is the cost of the pair of
Lisa [10]

<u>Answer</u>

20%


<u>Explanation</u>

let the cost of tie = x

Then cost of a pair of pants = (100+50)%x

                                               = 150%x

                                                 = 1.5x

The cost of shirt = (100+25)%x

                           = 125%x

                             = 1.25x

(1.5x - 1.25x)/1.25x × 100

0.25x/1.25x × 100

0.2 × 100 = 20%

Graph the function. For the function whose graph is shown below, which is the correct formula for the function? y = –x – 1 y = x
rusak2 [61]
You forgot to mention the graph.
So, I make the graph of both given functions and you will compare your graph with them.

First, y= -x-1  
put y=0 you get point (-1,0) called x-intercept
put x=0 you get point (0,-1) called y-intercept
join both the points, you will get the graph
Graph is attached in the picture.

Second, y= x+1
put y=0 you get point (-1,0) called x-intercept
put x=0 you get point (0,1) called y-intercept
join both the points, you will get the graph
Graph is attached in the picture.

For what value of r is the parallelogram a rhombus
Gre4nikov [31]

Answer:

9

Step-by-step explanation:

7r+18=r²

r²-7r-18=0

factorizing

r²+2r-9r-18=0

r(r+2)-9(r+2=0

(r-9)(r+2)=0

r-9=0

r=9

check

(r²)=(9*9)=81

7r+18=7(9) + 8=81
