Ok so you divide the bill by 2 because you each are paying half. You knock off $4 because you owed him that from last time and you pay $9. So this would equal to b/2 -4 =9. If you work it out in reverse, you get 4+9 which equals 13 then multiplied by 2 which means the total bill was $26.
So we have 5+3x=11. We subtract 5 from both sides and get 3x=6. we divide both sides by 3 and get x=2. Daniella skated for 2 hours
Answer:
look at the picture I have sent
Mean = Average

<span>4.59 · 10^-5 and 30
= (4.59 x 3) x 10^-4
= 13.77 x 10^-4
= 1.377 x 10^-3</span>
Volume of a cube is expressed by: V = a^3
So a = 0.6
V = (0.6)^2
V = 0.22 approx.
Hope this Helps! :)
