Step-by-step explanation:
5y + 2 +2y + 3 = 12 - 15
7y + 5 = 12y - 15
7y + 20 = 12y

Answer: 9
Step-by-step explanation: so first you remove the ( ) because they’re useless in this then once you remove then Since two opposites add up to zero, remove them from the expression then you only get left with 9.
81 divided by 4 is ....20.25
Answer:
I think that the answer is D. CB ║DE
To find the answer, all we need to is to calculate all the missing one.
So: ∠CBD = 180° - 60° - 40° = 80°
∠BDE = 180° - 60° - 40° = 80°
∠DEF = 180° - 60° - 45° = 75°
Since we have ∠CBD ≅ ∠BDE ( = 80°) and they are alternate interior angles, we can conlcude that CB ║ DE.
