Answer:

the correct solution has been explained

Step-by-step explanation:

Jackson,s reasoning is incorrect  because it should be 8 ones and not 8 tens that would give 64

\frac{640}{80} = \frac{64}{8} = 8

Moreover, \frac{637}{78}  is\ not\ equal\ to \frac{640}{8}

as \frac{637}{78}= 8.16

whereas \frac{640}{80} = 8

clearly, both quantities are different

Answer: G

Step-by-step explanation:

The total bottle sold on monday is so i'm gonna assume that 40 people were in the cafeteria that day. The cafeteria had 80 customers, which is double the amount of customers from yesterday. If we want to make predictions from monday's data, we should double all the values in the table (so basically apple juice is now 22, cranberry is 14, etc.) so it's more fitting to the number of customers on tuesday.

apple - 22

cranberry - 14

orange - 36

pineapple - 8

G is not supported because it says that 6 times more apple juice will be sold than cranberry. So if we look at the [modified} table, cranberry is WAY over half the amount of apple juice. This means that G's statement is not supported by the table

What is the soultion of - 21 = n - 8<br><br><br><br> what is n
xenn [34]
This is a simple equation:)
We have to isolate "n" to be alone. 
-21 = n - 8 

First add 8 to both sides. 
-21 = n - 8
+8  =    + 8 it cancels out on the right side of the equal side and you solve on the left side

soooo
-21 + 8 = -13
-13 = n 

Finally our answer is
-13 = n  



When in doubt, eat a pineapple:)

What is 0.95 rounded to the nearest hundread?
sasho [114]

0.95 rounded to the nearest hundredth (I assume that's what you mean) would still be 0.95. Since I saw your other question, I think you're looking for 0.095 rounded to the nearest hundredth, which is 0.10.
