Answer:
Juan has to work at least 21 weeks.
Step-by-step explanation:
Juan earns $3 a day, then he earns $21 per week.
Let x be the number of weeks Juan works. He will earn $21x in x weeks.
Juan has saved $213,
He earns $21x,
Juan's total earnings are $213+$21x.
He needs to save at least $654, so
Juan has to work at least 21 weeks.
Let's look at the math; half a disk takes 40 seconds to rip, and two halves make a whole, so 40 + 40 = 80 and that's your answer
Let the length of shortest side be - x
length of medium side - x +3
length of longest side - x +3 + 11
so , according to question
=> x + x +3 + x +3 + 11 = 59
=> x + x +x + 3 + 3 + 11 = 59
=> 3x = 59 - 17
=> 3 x = 42
=> x = 42/3
=> x = 14
Shortest side = x = 14
medium side = x + 3 = 14+3 = 17
longest side = x + 3 +11 = 14 + 3 + 11 = 28
