Alex

Answer:

The number of movies purchased is 5

Step-by-step explanation:

40.00 + 3.50 = 43.50

43.50 + 3.50 = 47.00

47.00 + 3.50 = 50.50

50.50 + 3.50 = 54.00

54.00 + 3.50 = 57.50

so if you add 3.50 to 40, 5 times you'll get 57.50

Hope it helped

Does someone know how to do this?
amid [387]

3√x+2 = √x+4

divide both sides by 3

√x+2 = √x+4 / 3

remove radical by squaring both sides

x+2 = x+4/9

x+2 = x/9 + 4/9 =

8x/9 = -14/9

8x*9 = -14*9=

72x = -126

x = -7/4
