5-x÷3=-7
Add 3 to both sides of the equation.
5x=3+7
Divide each term by 5 and simplify.
Divide each term in 5x=10 by 5
5x/5=10/5
Reduce the expression by cancelling the common factors.
x= 10/5
Divide 10 by 5
Answer <em>x </em>=2
Answer:
It will take the apprentice 24 days working alone
Step-by-step explanation:
Let the number of days it takes the apprentice be x
It will take the landscaper x/3 ( since he is three times faster)
The rate for both will be 60/6 = 10 sq m per day
Rate for apprentice is 60/x
rate for the boss is 60/x/3 = 180/x
Adding the rates together;
60/x + 180/x = 10
240/x = 10
240 = 10x
x = 240/10
x = 24 days
