Answer:
36 минут спустя в 7:21
это проблема LCM, поэтому вот как ее решить.
Том звучит через 9, 18, 27, 36 минут после первоначального звучания.
Звуки Эми в 12, 24, 36 минут
Итак, в 7:21, через 36 минут после того, как они ушли, и Том, и Эми проснулись, и они оба опоздали.

Translation
36 minutes later at 7:21am
this is a LCM problem so this how to solve it.
Toms sounds at 9, 18, 27, 36 minutes after it initially sounds
Amy’s sounds at 12, 24, 36 minutes
so at 721am 36 minutes after they went off both Tom and Amy when they woken up,they were both late.
step-by-step explanation: the increase = 204 - 120
increase = 84
percent increase = 84/120
percent increase = 70% so of course the percentage is 70% ( I hope this helps you )
Answer: 50 + 2x

Because the cost depends on the features
Answer:
3 hours was spent on labor
Step-by-step explanation:
<u>Key skills needed: Creating an equation, Solving an equation</u>
1) The total cost is 329.00 (or 329). The parts are 125.00 (or 125), and the labor is 68 per hour.
2) If we say h is the number of hours of labor, then we can create this equation -->
(or 68 multiplied by "h") 68h would be the cost of labor, and we need to find the number of hours (h) as a number.
3) We can create this equation -->
--> This equation can be made as the total cost (329) is equal to the parts (125) and the labor (68h)
4) Subtract 125 from both sides to get 68h by itself
--> 329 - 125 = 204 so 204 = 68h
--> Divide by 68 on both sides (204 divided by 68 is 3)
--> This means that h is 3.
Therefore, the number of hours spent on labor is 3.
