B because the other ones are just wrong because when you solve them, you get positive numbers
You know 100 cm is one meter. So you multiply 3.9 by 100 = 390
Plz mark mine the brainliest answer:) hope this helped
Answer:
The result is that you eliminate the 7y term and thus can solve for x.
x = -28/3
y = 30/7
Step-by-step explanation:
-20 + 7y = 10
3x + 7y = 2
subtract... elimination method
-20 - 3x = 8
-3x = 28
x = -28/3
-20 + 7y = 10
7y = 30
y = 30/7
I believe it would be a right triangle
