Adams arcade charges an entrance fee of $7.50 and 0.45 per game. Jims jamming does not charge an entrance fee but the games are $1.25 each. How many number of games must be played in order for the total cost of both arcades to be the same?

Step-by-step explanation:

cost of playing x games at Adams = 7.50 + 0.45x

cost of playing x games at Jims = 1.25x

1.25x = 7.50 + 0.45x

1.25-0.45x = 7.50

0.80x =  7.50

x = 7.50/0.80 = 9.375 , but x must be an integer.

The cost is never the same. When x ≤ 9, Adams costs more. When x ≥ 10, Jims costs more.

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.

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
