(5 + 3) / (-2 -8) = 8/-10 = -4/5
Step-by-step explanation:
x^2 + y^2 = r^2 --> r =
=
cos = x /r = -4 /
sin = y /r = 5/
tan = sin /cos = -5 /4
Reduce the common factors of the top and bottom of the fraction. You should be left with (-2d^2 ef^4)/3
Answer:
30 - (20% × 30) =
30 - 20% × 30 =
(1 - 20%) × 30 =
(100% - 20%) × 30 =
80% × 30 =
80 ÷ 100 × 30 =
80 × 30 ÷ 100 =
2,400 ÷ 100 =
24
