Question

I need help someone. Can someone please help me?

Answer 1

Write a word problem describing the time it takes to complete an activity individually
and with a friend.
For example, if John takes 2 hours to mow his lawn and it takes his sister Maria 4 hours to mow the same lawn, how long would it take John and Maria to mow the lawn together?

Write a rational equation based upon the word problem you created.

The rational equation based upon the scenario above would be \[\frac{ 1 }{ 2 } + \frac{ 1 }{ 4 } = \frac{ 1 }{ x }\]
Each fraction represents the amount of the lawn mowed in one hour. The fraction of \[\frac{ 1 }{ 2 }\] is John’s portion. Maria’s share is represented by \[\frac{ 1 }{ 4 }\].
The time it would take for both of them to mow the lawn is represented by \[\frac{ 1 }{ x }\].
Solve the rational equation. Show your work.

Hint:

\[x = \dfrac{4 \times 2}{4 + 2}\]

Answer 5

ok Which part is that a hint for? the 1st part?

Answer 6

Do you think you could help me with making a rational equation that goes with a scenario

Answer 7

So if we say that is takes John 2 hours to paint a room and it takes Mary 3 hours to paint the same room. How long would it take for them to paint the whole room together?

So would the expression be \[\frac{ 1 }{ 2 } + \frac{ 1 }{ 3 } = \frac{ 1 }{ x }\] ? @Hero
