Area of a circle = pi *r*2
Area of complete circle with radius of 2 is about 12.56
Divided by 2 is 6.28
2x-17= -3. Hope it helped
The answer to this question is 1:11.
Answer:
Multiply by -2
Step-by-step explanation:
Additive inverse essentially means the counterpart that negates a number. Then, elimination can be used. In this case, the easiest change would be with the terms -4y in the first equation, and -2y in the second equation, since 2 is a factor of 4. So,
3x - 4y = -5
5x - 2y = -6
The goal here is to cancel out the -4y.
(5x - 2y)(-2) = (-6)(-2)
-10 + 4y = 12
3x - 4y = -5
Now it works.
3/4z - 1/4z + 3 = 2/4z + 5
3/4z - 1/4z - 2/4z = 5 - 3
2/4z - 2/4z = 2
0 ≠ 2
