Step-by-step explanation:
Lets find the values:
<em>Gained</em><em> </em>2.2 kg = 2.2
<em>Lost</em><em> </em>1.5 kg = (-1.5)
<em>Lost</em><em> </em>3.7 kg = (-3.7)

1 of 3 kids was a boy, so (1/3)·75 = 25 were boys.
Answer:
Step-by-step explanation:
1) 4x -3
x = -7 ;
4x - 3 = 4*(-7) - 3 = - 28 - 3 = -31
x = 14 ;
4x - 3 = 4*14 - 3 = 56 - 3 = 53
x = 0
4x - 3 = 0 - 3 = -3
2) 6 -3x
x = -7 ;
6 - 3x = 6 - 3*(-7) = 6 + 21 = 27
x = 14
6 - 3x = 6 - 3*14 = 6 - 42 = -36
x = 0
6 - 3x = 6 - 0 = 6
