No! It equals 15, but 9-6=3.
5X + 9 5(3) + 9 15 + 9 = 24 ====
The commutative property.
-9
9 plus 135 = 16 The series is formed by dividing the second number by the first number and then adding 1 to the quotient. 18 ÷ 3 = 6 : 6 + 1 = 7 14 ÷ 7 + 2 : 2 + 1 = 3 18 ÷ 6 = 3 : 3 + 1 = 4 112 ÷ 8 = 14 : 14 + 1 = 15 135 ÷ 9 = 15 : 15 + 1 = 16
9/15 + 10/15 = 1 and 4/15
-9
3/5 + 1/3 is the same as 9/15 + 5/15 which equals 14/15
25+15=40+9=49
Collect like terms: 9a -7a = 9 - 15, ie 2a = -6, so a = -3
-7a+2a+9 is also -5a+9. -5a+9=24. -5a=15. a=-3.
d/3+3 = 5 d+9 = 15 d = 15-9 d = 6
