2. Marla can shovel the driveway in 60min and Bill can do it in 45min how long would it take them to do the job together?
3. Divide and simplify:
x^2-4/x divided by x+2/x+8
4. add and simplify:
5/49z^3 + 1/35z^2
5. simplify by removing factors of 1
y^2-5y+6/y^2+3y-18
6. divide and simplify:
h+1/h-3 divided by 6h+6/h-1(simplify answer)
7. add and simplify:
5/v-9 + 5/v+9
3 assembly lines can fill 24 orders in 10 hours , therefore in 1 hour 3 assembly lines can fill 2.4 orders (24/10) , consequently, 1 assembly line can fill 0.8 orders (2.4/3) in 1 hour. Therefore, 7 assembly lines can fill 5.6 (7×0.8)orders in an hour and thus the 7 assembly lines in 5 hours would fill (5.6 ×5)= 28 orders.
Therefore, the answer is 28 orders
