Answer 6

14 + 8 * 2 = 14 + 16 = 30
======================
[ (14 + 2) * 4 - 1 ] * 6 =
[ 16 * 4 - 1] * 6 =
[ 64 - 1 ] * 6 =
63 * 6 =
378
=======================
3(a + 2b) when a = 6 and b = 3
3((6 + 2(3)) =
3(6 + 6) =
3(12) =
36
=======================
quotient of number and 6 increased by 1
n/6 + 1
=======================
0.10d + 0.05n
======================
don't understand this one
======================
10 - x = 3x - 4
-x - 3x = -4 - 10
-4x = -14
x = 14/4 which equals 3.5
======================
D. h + (h + 3.5) = 18
