Yes they are because if you divide 18 by 3 you get six and if you divide 15 by 3 you get 5, so it simplifies to 6:3 which is the same as the ratio for rings
Answer:
2 hours.
Step-by-step explanation:
Money earned for 14 hours of life-guarding = 14*18 = $252. If he worked another 5 hours to make the maximum of 19 he would earn 252 + 5*9
= $297 but he wants to work a minimum of hours for a minimum of 270.
Thus we have the inequality:
252 + 9x ≤ 270
9x ≤ 18
x ≤ 2.
So the number of hours he must do clearing tables = 2.
Answer:
x + 5 divided by x - 5 = 10
Then we can solve it as
x + 5 = 10 ( x - 5 )
x + 5 = 10x - 50
Collecting the variables to one side & numericals to other side then the equation becomes
10x - x = 5 + 50
or 9x = 55
Therefore x = 55/9
