Just by trying some small numbers, you discover two that work: 3 and 5.
3 + 5 = 8
3² + 5² = 9 + 25 = 34 .
Experienced worker takes 4hr to complete so in 1hr it would be 1/4 completed.
Apprentice worker takes 12hrs to complete, so in 1hr it would be 1/12 completed.
Team effort X hours and 1/X part of the job completed in an hour.
Set up:
1/4 + 1/12 = 1/x
Get the denominators the same to add. So multiply the left side by 3.
3/12 + 1/12 =1/x
Combine like terms.
4/12 = 1/x
Cross multiply.
4x = 12
Dived by 4 on both sides
X = 3 hrs if they work together.
The answer is 3.
Муну ушундан көбөйтүшүңүз керек, андан кийин эмне болуп жатканын түшүнүш үчүн бөлүң!үз. балким, бул жерде, бул татаал нерсе. сиз тегерек болушуңуз керек, балким, ушул сыяктуу нерсени билип алыңыз?
Doa. :)
Answer:
the first month new members have to pay 188 dollars for the membership.
the equation is 160x+28=y
x stands for the number of months and y stands for the total cost.
for the first month [ membership starts] the total cost is 188$ . for the secind month the total money paid would be 348$. for the third month the total money would be 508$ .
and so on u can use the equation to solve for more months . just substitute x for the numbers of month u are solving for
