Answer:
Should be x/9
Step-by-step explanation:
Answer: 2 markers.
Step-by-step explanation:
1. You know that she gives 12 markers to Mr. Cooke, then the rest among is:
29 markers-12 markers=17 markers
2. She divides the rest among 5 other teachers and each one of them get the same number of markers. So, you need to divide 17 markers by 5 teachers as following:
17 markers/5=3.4 markers
3. But the number of marker each one teacher has can't be a decimal number, so this number must be: 3 markers for each teacher.
3. The number of markers that will be left over is:
17 markers-(5*3 markers)=2 markers

Answer:
24 minutes, 2:36 pm
Step-by-step explanation:
As working with hours is difficult because it does not use decimal system, lets work with minutes, not hours.
So, the clock is set to work normal at 3:00 pm and we need to get the minutes lost three days after. We know that, as 1 day has 24 hs, 3 days have 72 hours. Then, as our clock loses 2m after every 6 hs, we need to see how many 6hs are there in 72 hs. We do this bt dividing 72 by 6:
72/6 = 12
So, in 72 hours we will have 12 periods of 6hs. As our clock loses 2m after every 6 hs, in 3 days we will lose 2m 12 times. This is:
12 * 2 = 24
The clock loses 24 minutes.
Now we need to see the time it will read.
If there were no problems, the clock should read 3:00 pm after 3 days (72hs). But, as it lost 24 minutes, it will read 2:36 pm, it is, 24 minutes before 3:00 pm.
<span>1/4(x + 16) - x =
First, distribute the 1/4.
= 1/4x + 1/4 * 16 - x
= 1/4x + 4 - x
= 1/4x + 4 - 4/4x
= 1/4x - 4/4x + 4
= -3/4x + 4
