2 + 3 + 5 = 10
25 ÷ 10 = 2.5
2.5 × 2 = 5
2.5 × 3 = 7.5
2.5 × 5 = 12.5
5 : 7.5 : 12.5
-3 (x - 5) - 8 (y + 2) + (-3) (6 - 4b)
First, simplify your brackets. / Your problem should look like: -3 (x - 5) - 8 (y + 2) + -3 (6 - 4b)
Second, simplify. / Your problem should look like: -3 (x - 5) - 8 (y + 2) - 3 (b - 4b)
Third, expand your problem. / Your problem should look like: -3x + 15 - 8y - 16 - 18 + 12b
Fourth, simplify. / Your problem should look like: -3x - 8y + 12b - 19
Answer: -3x - 8y + 12b - 19 (D)
sin 30 = .5 and cos 60 = .5
sin 60 = sqrt(3) / 2 and cos 30 = sqrt(3) / 2
answer - cos 60 and cos 30
