Answer:
y= $1.50x
Step-by-step explanation:
Each bagel is $1.50,therefore for each family member(x) the amount increaes by the same rate
Answer:
fmmdmme,ekemmdm
Step-by-step explanation:
So work =time times rate or W=TR
so T=m-k
W=(m-k)R
if you want just m-k then m-k is the answer
To solve this problem you must apply the proccedure shown below:
1. You have the following expressions shown in the problem above:
(<span>8m^2-6/n+3) + (9m^2-4/n+3)
2. As you can see, they have equal denominators, then you have:
(</span><span>8m^2-6+ 9m^2-4)/(n+3)
</span><span>
3. Therefore, when you sum, you have the following result:
(17m</span>²-10)/(n+3)
<span>
The answer is: </span> (17m²-10)/(n+3)<span>
</span>
Answer:
This problem can be solved by working backwards.
Average of 30 students = 70.
Total marks of all the 30 students = 30x70 = 2100
Out of these 30, average of 20 students = 62
Total marks of these 30 students = 30x62 = 1860
So the total marks of the remaining 10 students = 2100-1860 = 240
Hence the average of the remaining 10 students = 240/10 = 24
