If: 5/6r = 2/3 then r = 5/4 or 1.25
21 4t2+6r-tr 4[-3]2+6[5]-[-3][5] 8[-3]+30-[-15] -24+30+15=21
2 over 3 equals 8 over 12
3+10-r+6r = -3+9r+0 13+5r = -3+9r 16 = 4r r = 4
6r * 5r^2 = 30r^3 ------------ multiply the bases and add the exponents ( 6r is really 6r^1, but the implied 1 is never written as mathematical convention )
It equals to 3 over 2
12 - 6r = 2r + 36Add 6r to each side:12 = 8r + 36Subtract 36 from each side:-24 = 8rDivide each side by 8:r = -3
It equals 3 over 6 which equals 1 over 2. Your welcome.
-6r + 1 = -17, then (17+1)=18=6r, so r=(18/6)=3. The answer is r=3
3/1=6/2
-2, 3

2/5 divided by 3/10 equals .4/.3 which equals 4/3 or 1.33333333
