Why can't the sum of any 4 consecutive numbers be a multiple of four?
anyanavicka [17]

It wouldn't be able to be because since all of the the numbers that could fit is probably going to be a decimal. Let's say we find 4 consecutive numbers of 32.

Equation:

x+(x+1)+(x+2)+(x+3)=32

4x+6=32

    -6    -6

4x=26

x=6.5 1. 6.5, 7.5, 8.5, 9.5

As you can see, the consecutive number is going to be a decimal.

Jessie sorted the coins in her bank. She made 7 stacks of 6 dimes and 8 stacks of 5 nickels. She then found 1 dime and 1 nickel.
ANEK [815]
Hello!

So, Jessie made 7 stacks of dimes and 8 stacks of nickels.

Each stack of dimes has 6 dimes.

Each stack of nickels has 5 nickels. Multiply:

6 × 7 = 42

8 × 5 = 40

Then she finds another dime and another nickel.

42 + 1 = 43

40 + 1 = 41

43 + 41 = 84

ANSWER:

Jessie has 43 dimes, 41 nickels, and 84 coins in all.

6 + x/3 = 1 <br> Step by Step explanation on how to solve this problem.
professor190 [17]

Answer:

x = -15

Step-by-step explanation:

6 + (x/3) = 1   (subtract 6 from both sides)

(x/3) = 1 - 6

x/3 = -5  (multiply both sides by 3)

x = -5 (3)

x = -15
