Find two numbers, if … c Their sum is 3/5 and their difference is 7 1/5

39/10 and - 33/10.

Step-by-step explanation:

7 1/5 = 36/5  so if the 2 numbers are x and y, we have:

x + y = 3/5

x -  y =  36/5      

Adding the 2 equations to eliminate y:

2x =  39/5

x = 39/10.

So 39/10 + y = 3/5  (from the first equation).

y = 3/5 - 39/10

y = 6/10 - 39/10

y = -33/10.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

the answer is 9.8975

explanation:

when you multiply the "39.59" with the 25% it reduces it and shows its final discounted price. hope this !
