The opposite of 3.5 is -3.5
C.24 is supplementary to 7
Answer:
∠ a = 60° , ∠ b = 120°
Step-by-step explanation:
Supplementary angles sum to 180° then
x - 40 + x + 20 = 180 , that is
2x - 20 = 180 ( add 20 to both sides )
2x = 200 ( divide both sides by 2 )
x = 100
Then
∠ a = x - 40 = 100 - 40 = 60°
∠ b = x + 20 = 100 + 20 = 120°
4 x
5 20
80/5=16
20(total questions)/5(total questions, simplified)=4
Multiply 4 by 4(correct questions).
The second method is better for a student in elementary!
