Answer:
you would divide 28 by 8 and get 3.5. so around 3:30 per song
Step-by-step explanation:
<span>Multiple: 9 * <span>8/9</span> = (<span>9*8/1*9) </span>= <span>72/9</span> = 8/1 = 8
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator <span>GCD(72, 9) = 9</span></span>
Answer:
r=3
Step-by-step explanation:
3(r - 7) = 4(2 - 2r) + 4
Distribute
3r -21 = 8 -8r +4
Combine like terms
3r -21 = 12 -8r
Add 8r to each side
3r +8r-21 = 12 -8r+8r
11r -21 = 12
Add 21 to each side
11r -21+21 =12+21
11r = 33
Divide each side by 11
11r/11 = 33/11
r = 3
