102
Why an approximate value when you know the exact value is 90! To the nearest thousand, for example, it is 0.
102. 12+90=102.
90
90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
702
7.8 + 12 = 19.8
90
10% of 90 = 990% 0f 10 = 9(10% of 90) + (90% of 10) = 18
If a + b + c + d + 80 + 90 = 100, then a + b + c + d = -70.
The value of x that solves the equation -243 = 90 - 9x is x = -12.
-90
The Republic of the Philippines' population has now reached up to 90 million. Note: This is an approximate value.
