(-1)*(-15) = +15 so -15 = + 15/(-1) So 15/(d-7) - 15/(7-d) = 15/(d-7) + 15/[(-1)*(7-d)] = 15/(d-7) +15/[-7+d] = 15/(d-7) + 15/(d-7) = 30/(d-7)
7
.15 times 7 = 1.05
7/15 in decimal form = 0.4666...7/15:= 7 ÷ 15= 0.4666... in decimal
7 over 15 is the same as 7 divided by 15: 7 ÷ 15 = 0.4667
8
15-7=8 15=7+8
7 over 15 is the same as 7 divided by 15: 7 ÷ 15 = 0.4667
The greatest common factor of 7 and 15 is 1. 1*7=7 1*15=15
3x+7=15 -7 -7 3x=6 (Divide) 3 3 x=2 Check it: 3(2)+7=15 6+7=15 15=15 :D
.15 times 7 = 1.05
(15)7 = 170,859,375
