Opposite number is the same number with the opposite sign:
So the opposite of
is
, since the original number is positive
opposite of
is
, since the original number is negative
Let the sons age = x
The dads age would be 3x ( 3 times the sons age)
X + 3x = 48
Simplify:
4x = 48
Divide both sides by 4
X = 12
The sons age is 12
Supplementary angles are angles whose sum is equal to 180°.
Let one angle be x
The other angle is said to be 26°more than the other so it is x + 26
x + (x+26) = 180
x + x + 26 = 180
2x = 180 - 26
2x = 154
x = 154/2
x = 77
1st angle, x, is equal to 77°
2nd angle, x + 26°, is 77° + 26° = 103°
77° + 103° = 180°
180° = 180°
If you doing it too fractions just if your trying too get a smaller number just divid what ever number too the bottom and top and if you want to go up(higher)just multiply by whatever you do too the top do too the bottom
