Elodia [21]

Answer:

7

Step-by-step explanation:

Given that there are 5 number cards.

They are 2,5,7,8,9

Total of all numbers in the cards = 2+5+7+8+9= 31

One card is removed say with number x.

Now sum new would be =31-x   ..  i

Average of remaining 4 cards = 6

So sum of remaining 4 cards = 6(4) = 24 ... ii

i and ii represent the sum of remaining 4 cards. Hence they should be equal

31-x =24

Subtract 31 from both sides to get

-x=-7

Or x =7

Of the cars in the parking lot, 20% are silver. If 20% of the cars is 48 cars, what is the total number of cars in the parking l
astraxan [27]
To solve this, we are going to set up a simple rule of three: If 20% are 48 cars, 100% how many cars will be:
\frac{20----\ \textgreater \ 48}{100----x}
Now, we can express this as a proportion ans solve for x:
\frac{20}{100} = \frac{48}{x}
x= \frac{(100)(48)}{20}
x=240

We can conclude that there are 240 cars in the parking lot.
