Step-by-step explanation:
8% of 24

24.00 + 1.92 = 25.92
27/10=2.7
Radians are the arc of circle divide by 10.
Answer:
x = -3
y = 7
Step-by-step explanation:
x + 3y = 18
-3x - 12y = -75
multiply first equation by 4
4 × (x + 3y) = 18 ➡ 4x + 12y = 72
now add the two equations up
4x + 12y - 3x -12y = 72 - 75 (-12y will eliminate 12y)
x = -3
