Lisa takes 3 hours to mow the lawn, while her cousin, barb, takes 2 hours. how long will it take them working together?

t=

t=72 minutes

Step-by-step explanation:

If it takes Lisa 3 hours to mow the lawn, then she mows 13 of the lawn per hour. Barb takes 2 hours to do it alone so she completes 12 of the lawn each hour. Working together, they mow the lawn in some time t. This can be written as

+=

Multiply each side by the least common denominator, 6t.

6t(+)=6t()

Simplify and solve.

2t+3t=6

We can multiply the fraction by 60 to convert the fraction of an hour to minutes.  

t= (60 minutes)

To mow the lawn, it takes the two working together

t=72 minutes.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
