Answer:
angle 1 = 120 degree
Step-by-step explanation:
75 degree + 45 degree = angle 1 (sum of two opposite interior angles is equal to the exterior angle formed)
120 degree = angle 1
Answer:
B
Step-by-step explanation:
I believe the answer is B because if we multiply the top equation by 6, we get 48x + 30y = -42, and if we multiply the bottom equation by -5, we get
35x - 30y = 20. So now, if we add it all together, then the positive 30y and negative 30y cancel out aka it equals 0, and thus the variable y is gone, satisfying the requirement that the problem asks for ("Which of these strategies would eliminate a variable...").
I hope this helped, and if it's correct, I'd appreciate if you marked my answer as Brainliest :)
Answer:
2x+9
Step-by-step explanation:
You have to combine like terms. 2x stays the same because there are no other like terms, but 5, 2, and 2 can be added together to make 9
Answer:
3 and 2
Step-by-step explanation:
3 x 2 = 6
3 + 2 = 5
Answer: D
Step-by-step explanation:
As you can see it is switch from -3 to 3.
Why?
Because each time it is being multiplied by -1 so it switches from negative to positive and geometric sequences involve multiplication (and division so technically it could be dividing by -1).
