Daniel's age is X
Daniel's brother age is Y
X = 3 + ( 2Y )
Y = ( X - 3 ) / 2
In case of Daniel is 17
then his brother's age is = ( 17 - 3 ) / 2 = 7 years
The answer is B.
B is the answer because:
2(1)-8= -6
2(2)-8= -4
2(3)-8=-2
2(4)-8=0
So u have 5 fruits and 3 bowls
Divide 5 into 3 that would equal how many grams you would put in one bowl then measure that and then complete it by adding that amount into each bowl
