To solve, follow the formula Volume = Length · Height · Width. If you are solving without a calculator, simply multiply the length and the height first, then multiply the product of that by the width, 2 / 3. V = 10 · 9 · 2/3 V = (10 · 9) 2/3 V = 90 · 2/3 <span>V = 60 in.³ </span> Hope this helps. Good luck! :)
So assuming that the total =27 r+b=27 r=-5+3b r=3b-5 subsitute 3b-5 for r in first equation 3b-5+b=27 4b-5=27 add 5 4b=32 divide by 4 b=8 subsitute b+r=27 8+r=27 subtracct 8 r=19
