Step-by-step explanation:
We check for a point where the y coordinate isn't four times the x coordinate.
Answer:
LCM of 5, 10, and 12 is 60
6, 10, and 12 is 60
2, 4, and 9 is 36
This is how I would solve it:
1st # = x 4(x+1)=3x+18
2nd # = x+1 4x+4=3x+18
4x=3x+14
x=14
To check: 15x4=60; 60-42=18. <u>1st # = 14; 2nd # = 15.</u>
Answer:
9 cents per day
Step-by-step explanation:
1 week = 7 days
Each razor lasts 1 week = 7 days
10 razors last 10 weeks = 10 * 7 days = 70 days
cost per day = (total cost)/(number of days)
cost per day = $6.30/(70 days) = $0.09/day
(7 × 10-21) / (<span> 7.6 × 10-22) = 9.21 times greater</span>
