Answer:
p >5 or p <-8
Step-by-step explanation:
-6+|2p+3|>7
Add 6 to each side
-6+6+|2p+3|>7+6
|2p+3|>13
We get a positive and negative solution
2p +3 > 13 and 2p +3 < -13
Subtract 3 from each side
2p +3 -3> 13-3 or 2p +3-3 < -13-3
2p > 10 2p < -16
Divide by 2
2p/2 > 10/2 2p/2 <-16/2
p >5 or p <-8
so two fellows did all the carpeting in 10 days.
now, how long did "1" fellow work only? well, it worked for 10 days.
how long did the other fellow work for? well, it was working alongside the first one, and it was there for also 10 days.
so the two guys working together, really did 10+10 = 20 "days worth of work". So that the whole carpeting job can be done in 20 "days worth of work".
now if we want to finish it in 4 days, 20 ÷ 4 = 5.
so if we hire 5 guys, since each one will do 4 days worth, 5*4 = 20 <- the whole job.
Answer:
3) C) $792.50
4) D) $707.50
Step-by-step explanation:
3) Home price = $ 253,600
Mortgage rate = 3.75% APR
Therefore, monthly rate = 3.75% divide by 12
= 0.0375/12
= 0.003125
1st month interest = principle * 0.003125
= 253600*0.003125
=$792.50
3) Answer: $792.50
4) You paid $1500
The first monthly interest = $792.50
Principal paid in the first month = 1500 - 792.50
= $707.50
Answer: D) $707.50
