The sum of three consecutive numbers is 72. What are the smallest of these numbers?
lisov135 [29]

let "a number" = x

(x) + (x + 1) + (x + 2) = 72

Simplify. Combine like terms

3x + 3 = 72

Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.

3x + 3 (-3) = 72 (-3)

3x = 72 - 3

3x =  69

3x/3 = 69/3

x = 69/3

x = 23

23 is the smallest number

hope this helps

The number 2017 can be expressed as the difference of the squares of two consecutive whole numbers. What is the sum of these two
SSSSS [86.1K]

Let x be the first number

X + 1 be the second number

So

(x+1)^2 – x^2 = 2017

X^2 + 2x +1 – x^2 = 2017

2x + 1 = 2017

2x = 2017 – 1

2x = 2016

X = 1008

X + 1 = 1009

Sum = 1008 + 1009 = 2017

The answer is 3x^2-19x+1

(-4x+3)-(7x-3x^2-1)
-12x+7x+3x^2+1

Combine like terms:
3x^2+(-12x+-7x)+1
= 3x^2+-19x+1
