Answer: 17, 19, 21 and 23
Step-by-step explanation:
Let x-3, x-1, x+1 and x+3 be 4 consecutive odd numbers.
Now,
According to question, their sum is 80.
x-3 + x-1 + x+1 + x+3 = 80
4x = 80
x = 20
Four consecutive odd numbers are,
x-3, x-1, x+1 and x+3
20-3, 20-1, 20+1 and 20+3
17, 19, 21 and 23
Im mot sure of the answer
Answer:
<em>The employees will work for 1 hour, will earn $5 per hour and will be paid $5</em>
Step-by-step explanation:
<u>System of Equations</u>
The number of hours the employees work is x.
And the hourly wage that they are paid is y. The store manager is willing to pay the employees a wage given by the equation
10y-30x=20
The business owner states that the employees should be paid a wage given by the equation
6y+30x=60
Adding both equations we have:
16y = 80
Dividing by 16:
y = 80/16 = 5
Substituting into the first equation:
10*5-30x=20
Operating and simplifying:
50-30x=20
50 - 20 = 30x
30x = 30
x = 30/30 = 1
Thus, the employees will work for 1 hour, will earn $5 per hour and will be paid $5
Answer:
4 workers x 1 hour = 4 work hours
4 work hours/3 workers = 4/3
(4/3) x 60 minutes = 80 minutes
Answer it will take three workers approximately 80 minutes to trim a hedge.
