Answer:
78
Step-by-step explanation:
Smallest square: 1
Small Square: 2, Area of 4
Mid Square: 3, Area of 9
Mid White Square: 5, Area of 25
Big Square: 8, Area of 64
1 + 4 + 9 + 64 = 78
8x12=__?
14.900
in 849 the 9 is not under 5 so we move it up and make the 4 a 5 and then its exactly five so we can make the 8 a 9 then cancel everything below it to a zero.
x=-5/6 , 6
See below.
40 + 15x = 30 + 19x
15x - 19x = 30 - 40
-4x = -10
x = 2.5
Two and a half hours.
