Answer:
23
Step-by-step explanation:
sin
(55)/a = sin(20)/10
Answer:
20
Step-by-step explanation:
4(4)+3(4)-2(4)=20
4x + 2y = 20
3x - y = 10
Multiplying second equation by 2.
6x - 2y = 20
Adding to the first,
10x = 40
x = 4
y = 3x - 10 = 3(4) - 10 = 2
Answer: (4, 2)
Check:
4(4) + 2(2) = 16+4 = 20, good
3(4) - 2 = 12 - 2 = 10, good
Answer: 4
WHY?
Well 3, 7, and 9 are all ODD numbers BUT 4 is a even :3
