What is x, the amount of time painted by Lisa?

Answer 1

The Answer Is C

Explanation:

Answer 2

Explanation:

Lisa=x (1)

Beth=1.35x (2)

Tim=1.23x (3)

Lisa + beth + tim = 24 (4)

Replaced (1) , (2) and (3) in (4)

x+1.35x+1.23x =24

3.58x=24

x=24/3.58

x=6.7

So replaced the x value in (1) , (2) and (3)

Lisa= 6.7 hours

Beth=1.35(6.7)

Beth=9.1 hours

Tim=1.23(6.7)

Tim= 8.25 hours

To ckeck if the equation is correct 6.7+9.1+8.25=25

The answer is Lisa painted for 8.7 hours
