3/5 (10+5x)−1/3(6x+3)=9 ok answer fast
1 answer:
Answer: x = 4
<u>Step-by-step explanation:</u>
<em>multiplied by common denominator</em>
3(10 + 5x)(3) - 1(6x + 3)(5) = 9(15) <em>reduced all fractions</em>
90 + 45x - 30x - 15 = 135 <em>distributed</em>
15x + 75 = 135 <em>simplified (added like terms)</em>
15x = 60 <em>subtracted 75 from both sides</em>
x = 4 <em>divided 15 from both sides</em>

If the first gardener can finish the job in 6 hours, it means that every hour he completes 1/6 of the job.
By the same logic, the second gardener completes 1/7 of the job per hour.
So, if they work together, they complete
of the job per hour.
So, after 42/13 of a hour, they'll complete the job. Since one hour is made of 60 minutes, 42/13 of a hour is
So, it will take them about 194 minutes to finish the job, i.e. about 3 hours and 14 minutes.
