Answer:
7.5 days
Step-by-step explanation:
A working = 10 days
AB working = 4 days
AB = 4 --> 10B = 4
/10 /10
B = .4
AB = 3
A(.4) = 3
/.4 /.4
A working alone = 7 .5 days
<em>*pretty much solve for B and then equal AB to the amount of days the worked together before B left, 3 days, then it gives you the amount of time A must work to finish the house alone*</em>
You could drive 1,320 miles on 60 gallons of gas
The properties are the addition, multiplication, and division.
You use them without knowing when you solve an equation
2x+4=17
The addition property is subtracting the 4
The division is dividing the two
