The total amount of lawns to be mowed would be 20 in 35 hours.
Step-by-step explanation:
It takes an hour and 45 minutes to mow one lawn. When you multiply the 7 hours by 5 you get 35 hours. Same thing if you multiply the 4 lawns by 5 you get 20 lawns.
-2n-24=-8(2n-4) Multiply both sides by -1 2n+24=8(2n-4) Distribute the right side 2n+24=16n-32 Subtract 2n from both sides 24=14n-32 Add 32 to both sides 56=14n Divide 14 from both sides n=4
