The sum of 5 consecutive even numbers is 310. What is the third number in this sequence?
Answers
To find the other 4 numbers, since they are all even, sinply add 2 to the middle number to find one, add 2 to that to find another, subtract 2 from the middle number to fine the third, and subtract 2 from that to find the final one.
62 + 2 = 64
64 + 2 = 66
62 - 2 = 60
60 - 2 = 58
so your numbers are 58, 60, 62, 52, and 66. Together they add up to 310.
(I may have done this a non-standard way, bit it was the way that made the most sense in my head.)

Answer:
x =
Step-by-step explanation:
10 = 6*(x -4)
10 = 6*x - 6*4
10 = 6x - 24
Add 24 to both sides
10 + 24 = 6x - 24 + 24
34 = 6x
6x = 34
Divide both sides by 6
6x/6 = 34/6

Weight of the container in which Mr. Sand places the cube = 1/16 pounds
Weight of the cubed cheese and container together = 1 1/4 pounds
= 5/4 pounds
Then
Amount of cubed cheese placed by Mr. Sands = (5/4 - 1/16) pounds
= (20 - 1)/16 pounds
= 19/16 pounds
So
The quantity of more cheese that
Mr.Sands need to add to the scale = (7/4 - 19/16) pounds
= (28 - 19)/16 pounds
= 9/16 pounds.
From the above deduction we can easily conclude that Mr. Sand needs to add 9/16 pounds of cubed cheese to fullfil the order placed by Veronica.
Answer: 9/16
Step-by-step explanation:
First, we must find the answer to the hidden question: How much cheese did Mr. Sand put in the container without the weight of the container? We can rename 1 1/4 to 1 4/16, so 1 4/16 - 1/16 = 1 3/16
Now we must find the amount of cheese that needs to be added. We can rename 1 3/4 to 1 12/16 by multiplying it by 4/4. 1 12/16 - 1 3/16 = 9/16
9/16 pound of cheese should be added to get the amount Veronica asked for.

It is impossible to add odd numbers (1, 3, 5, 7, 9, 11, 13, and 15) and odd number of times (3) to get an even number (30)
Step-by-step explanation:
1, 3, 5, 7, 9, 11, 13, and 15 are all odd numbers and 30 is an even number
When odd numbers are added even times the answer is always even for example 3 + 5 = 8, and when odd numbers are added odd times the answer is always odd for example 1 + 5 + 7 = 13
It is not possible to add three odd numbers to get an even number
Where x = odd therefore x + 1 = even = y say
hence 2 × x = 2×(y-1) = 2·y - 2 = even number
Also 3 × x = (3y -3) = odd number
Answer: The answer is 7+(3+5)+15 = 30
