How is this Trig ???
anyway
Lisa --- x
Beth ---- (8/5)x
Tim --- (5/3)x
x + (8/5)x + (5/3)x = 24
multiply by 15 , the LCD
15x + 24x + 25x = 360
Now it becomes very easy to solve for x
Lisa, Beth, and Tim painted their grandparent's house.
• The amount of time Lisa painted can be represented by x.
• The amount of time Beth painted is 1 3/5 times the amount Lisa painted
• The amount of time Tim painted is 1 2/3 times the amount Lisa painted.
• The total amount of time Lisa, Beth, and Tim painted is 24 hours.
What is x, the amount of time painted by Lisa?
