The sum of three consecutive numbers is –15. What is the LARGEST number?

soldier1979 [14.2K]

Consecutive numbers are numbers that follow one right after the other. One example is the set {6, 7, 8}. We don't know the three consecutive numbers so let's define...

x = first number
x+1 = second number
x+2 = third number

where x, x+1, and x+2 are consecutive numbers

-----------------------------------------

"The sum of three consecutive numbers is -15" meaning that
x+(x+1)+(x+2) = -15

Let's solve for x
x+(x+1)+(x+2) = -15
x+x+1+x+2 = -15
3x+3 = -15
3x+3-3 = -15-3
3x = -18
3x/3 = -18/3
x = -6

So this means

first number = x = -6
second number = x+1 = -6+1 = -5
third number = x+2 = 6+2 = -4

The list of consecutive values is {-6, -5, -4}

They add up to (-6) + (-5) + (-4) = -11+(-4) = -15
which confirms we have the right values

---------------------------------------------------------

In short, the final answer is -4

Egal loggers got away with 4 acres of trees at a reserve in central Mexico. That number represents a 97 percent decline from two

geniusboy [140]

Answer: with 133.33 acres of trees

Step-by-step explanation:

4 acres of trees, is a 97% decrease of the previous amount.

This means that if the previous amount was X, then 4 acres is 3% (or 0.03 in decimal form) of X, or:

4 acres = 0.03*X

Now we can solve this for X as:

X = 4acres/0.03 = 133.33 acres

The illegal loggers got away with 133.33 acres of trees
