You have to change it to algebraic form so the equation will be
3P + 2B = 23
2P + 8B = 52
yeah it should be easy to figure out like that
Answer:
<u>1 gallon / 600 sq ft</u>
Step-by-step explanation:
As we can see, we are given that 600 sq ft uses one gallon to cover, therefore one gallon covers 600 sq ft (just vice versa of what's given).
Data on first test: 50, 50, 50, 50, 50
Mean = 250 / 5 = 50
In the next test, Data is: 50, 50, 50, 50, 100
Mean = sum of data / number of data
Mean = 50 + 50 + 50 + 50 + 100 / 5
M = 300 / 5
M = 60
In short, Your Answer would be 60
If You're looking for combined progress (average of class then, it would be: 50 + 60 /2 = 110/2 = 55
Hope this helps!
For this problem, we can know that 1 over 3 is same as 4 over 12, and 2 over 3 is same as 8 over 12, so, that 7over 12 is greater than 1 over 3 but less than 2 over 3. hopes it can help you ~
