Answer:
Both are right.
Step-by-step explanation:
The two are both right.
Multiplication in algebra obeys the cummutative law ( a * b = b * a).
8/4=12/x
Would be the ratio.
Solve it:
8/4 =12/x
2=12/x
2x=12
X=6
Let n be the amount of time it takes william to cut the lawn. Then Shelly takes
n-2 hours. So:
1/n+1/n-2=1/3
3(n-2)+3n=n²-2n
6n-6=n²-2n
n²-8n+6=0
Using the quadratic formula, we get a positive value of 7.1623 hrs as the amount of time william takes working alone, and 5.1623 as the amount of time Shelly takes working alone
