Easy. their total weight is/was 7.78 kilograms. they threw the 54.5 cm to htrow you off
74% means 0.74
"of" means "times"
So, 128 = 0.74 times (the number)
Divide each side of this equation by 0.74 :
128/0.74 = the number
<em>172.973</em> (rounded) = the number
The answer is A..... 2 2/3
Watch carefully:
A 'zero' of the function is a value of 'x' that makes the function zero.
2x - 10 = 0
Add 10 to each side:
2x = 10
Divide each side by 2 :
x = 5
f(5) = 0
8 would become the whole number, since there are 3 repeating numbers you would put those over 999.
So you would get 8 and 132/999
