There are six teddy bears each teddy bear weight 7.04 how is the difference of the total weight of 7 teddy bears and 10 teddy

The difference is 21.12

Process:

Unit Rate is 7.04 for 1 teddy bear

7.04 × 7 = 49.28 <For 7 teddy bears

7.04 × 10 = 70.4 <For 10 teddy bears

Now we subtract to find the difference.

70.4 - 49.28 = 21.12

So the difference between the weight of

10 teddy bears and 7 teddy bear is

21.12.

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

47 - 90 = 43

43 - 180 = x

x = 137
