2y + 2x = 6
2y - x = 12
Subtract
3x = -6, x = -2
2(-2) + 2y = 6
-4 + 2y = 6
2y = 10, y = 5
Final solution: x = -2, y = 5
Answer:
Well, x=3, -3
Step-by-step explanation:
If you use a calculator you'll easily be able to figure this out.
Answer:
0.646 radians to the nearest thousandth.
Step-by-step explanation:
To convert degrees to radians we multiply by π/180
= 37 * π/180
= 0.20556π radians
= 0.646 radians to the nearest thousandth.
B) -15.6,-12.9,-10.2,-7.5,-4.8
This is an arithmetic sequence.
Answer:
20. 4n+5+8n-5=180(linear pair)
12n=180
n=15
21. 9x-6=8.5x+2(can be seen from image)
9x-8.5x=2+6
0.5x=8
x=8/0.5
x=80/5
x=16
22. 4z+3z+6=90°(Complementary)
7z+6=90°
7z=84°
z=12°
