10% = 1/10 15 + ((1/10)(15) = x 15 + 1.5 = x x= 16.5
If: x+10 = 15 then x = 5
If: x/3 + 10 = 15 Then: x = 15
x-10=15 Add 10 to both sides x=25
10 x 15 x 8 = 1200 in3
150 10 x 15 = 150 15 x 10 = 150 25 x 6 = 150
15 x 10-3 = 15 ÷ 103 = 15 ÷ 1000 = 0.015
-15
Yes.Proof:1 thousand = 10^31 billion = 10^915 thousand million = 15 x 10^3 x 10^6 = 15 x 10^9 (hint add the exponents)15 billion = 15 x 10^915 x 10^9 = 15 x 10^9 = True!!==========Orginal Answer:Yes, 15 billion is equal to 15 thousand million.15 billion = 1500000000015 thousand million = 15000000000thus 15 billion is equal to 15 thousand million
15 x 13 = 195A simpler way of breaking this down is:15 x 13 =(10 + 5) x (10 + 3) =(10 x 10) + (10 x 3) + (10 x 5) + (5 x 3) =100 + 30 + 50 + 15 = 195
15 ÷ 0.1 = (15 x 10) ÷ (0.1 x 10)= 150 ÷ 1= 150
X/10 * 15/25 = 6 x=6
