If you solve it into point-slop form, the equation is y = -3x + 20, then put into standard form is 3x + y = 20. That's your answer.
Group A I’m pretty confident with that answer
Answer:
It should be 0.88
Let me know if I'm wrong!
Answer:
42
Step-by-step explanation:
i said so
<span>x-y=2y -> x=3y and
3x-40+2y=180 --> 9y-40+2y=180 --> 11y=220 --> y=20, x=60 --> <A=<C=140 degrees, <B=<D=40 degrees.</span>
