Let N be the number
4(N + 5) = 35 simplify
4N + 20 = 35 subtract 20 from each side
4N = 15 divide both sides by 4
N = 15/4 = 3.75
1/2x-3=3/2x+4 subtract (1/2)x, 4 from both sides
-7 = x
Add all your values together then divide by the number of them
3/15 = 1/5 = .20 = 20%
530 mod 360 = 170°
180 - 170 = 10° angle in the second quadrant
Using I = Prt, we have......
$12047 x .035 x (10/12) = about $351.37
5{[5(q-5)+15]-[3(5q-2)+5]}
5{[5q - 25 + 15] - [15q - 6 + 5 ]}
5{[ 5q - 10] - [15q - 1] }
5 [ -10q - 9]

(x/sinx) * cosx =
x * [ cosx / sinx] =
